Research Activities
Being the Director of the Microwaves and Fiber Optics Lab of the National technical University
of Athens (MFOL-NTUA) from its establishment in 1984, my research activities cover a wide
spectrum of topics that are the subject of the general and broad research activities of the
Lab. The following areas are within my range of research activities:
• Ι. Applied Electromagnetic Theory
• II. Wireless Telecommunication Systems in microwave and millimeter wave
frequencies
• ΙΙΙ. Radars and Remote Sensing Systems
• IV. Biomedical Engineering
• V. Optical Systems
I started my career as an “Electromagnetist”, which I consider the fundamental scientific
discipline of Physics and Electrical Engineering and I have been involved in numerous
research topics such as telecommunication systems, sensors-radar and biomedical
engineering. Although I started as a theoretical researcher in the Hellenic Navy, I was able to
turn to experimental research as well.
Starting my research career in mid-1970’s, it was a time when scientific computations using
digital computers extensively were starting to establish in various fields. However, my
research in solving complicated electromagnetic problems proved the necessity of making the
best use of analytical tools such as integral equation solutions of complicated electromagnetic
problems. During the period of 1976-86 I was involved in research solving formidable
electromagnetic structures such as:
- One of the first approaches to solve the “microstrip antenna” radiation problem using
Green’s Function Theory (N.K. Uzunoglu, N.G. Alexopoulos and J.G- Fikioris,
“Radiation Properties of Microstrip Dipoles" IEEE Transactions on Antennas and
Propagation, vol. AP 127 No.6, pp.853-858, 1979)
- The scattering problems within dielectric and fiber optic waveguides (N.K. Uzunoglu,
"Scattering from Inhomogenities inside a Fiber Waveguide" Journal of the Optical
Society of America, vol.71, No.3, pp.259-273, 1981). This publication received the
International Marconi Award in 1981.
- Scattering of electromagnetic radiation (microwaves or optical) from non-spherical
particles.
In the following further information on the above topics is given in brief.

Ι. Applied Electromagnetic Theory
In the framework of my PhD Thesis I studied extensively the electromagnetic waves
scattering phenomena from non-spherical scatterers especially targeting the microwaves and
millimeter waves propagation through rainy environment. In cooperation with Dr. Α. Holt, we
developed a new method of solving scattering problems using integral equations in the
spectrum domain with the use of computational algorithms. During my career I used this
specific method quite many times for modelling and solving various electromagnetic
structures. After 1976 I studied various structures such as antennas, waveguides, circuits and
more generic structures of interaction between the electromagnetic waves and natural beings
or artificial constructions. The subjects of this research cover a very wide spectrum of topics
such as antenna design in various geometries and technologies, various types of waveguides
either in conductive or dielectric materials, microwave devices and signal processing along
with the in depth study of the interaction phenomena of the electromagnetic waves with
biological tissues and mainly the human body.
The theoretical tools that were developed in the framework of the above work are related to
the following:
• Green function theory
• Integral equations and solving of EM problems using the Method of Moments – Galerkin
Technique and FEM.
• Perturbation methods.
• EM wave propagation in complex materials and dielectric substrates
• EM modelling of monolithic passive and active structures (to be applied in MMICs)
• Development and optimization of hybrid techniques of computational electromagnetism
for solving microwave and millimeter wave problems,
• Computational electromagnetism with parallel processing and high performance
algorithms for solving complex and large scale EM problems.
II. Wireless Telecommunication Systems in microwave and millimeter wave
frequencies
During my job occupation in the Hellenic Navy Research Center I systematically studied the
design and development of control and telecommunication systems of the Hellenic Navy
especially in the field of short and ultra short waves.
Coming to NTUA, I was involved with the design and development of telecommunication
systems prototypes of microwave and millimeter wave frequencies and fiber optics in the
framework of quite many research projects funded by EC and the Hellenic public sector. My
involvement in EC research projects started early enough in the framework of RACE, ESPRIT
programs and continued very actively in the last 15 years with the Calls of 5 ου , 6 ου and 7 ου EC
Framework Programs. In the framework of these EC funded projects I have been served
quite many times either as Scientific Responsible of the MFOL-NTUA related contribution or as
Principal Investigator and Senior Researcher. Furthermore, I have served as overall Project
Coordinator in quite many STREP but also Integrated Projects (IP) of these EC funded ones.
In parallel to my involvement in EC funded projects, I have been contributed in various and
many national projects (EPET, PABE, PENED, AKMON etc) funded by the Hellenic General
Secretariat of Research and Technology of the Greek Ministry of Education, Lifelong Learning
and Religious Affairs but also research assignments of Hellenic commercial companies and
the private sector. The main emphasis was on the development of fast electronic microwave
circuits in very high microwave frequencies along and in millimeter wave ones.
For that reason, a large investment infrastructure was made at the MFOL-NTUA along with
the establishment of the Photonics Lab which was based on an ATT Inc donation. Other
associated sub-labs were created such as the Radars and Remote Sensing lab directed by a

member of staff of MFOL, Prof. Panayiotis Frangos. This entire infrastructure gave the
opportunity of large development of the MFOL-NTUA in the area of microwave, millimetre
wave and optical telecommunications and a variety of related research topics.
Based on the above I work until present date in the following areas:
RF Microwave and Millimeter Wave technologies and circuits: Design and
development of microwave and mmwave systems and sub-systems (Power amplifiers,
LNAs microwave passive filters etc) and development of relevant simulation tools. Design,
simulation, development and characterization of MMICs and hybrid (MICs) wireless RF
circuits. Development of system analysis in macros environment for specs definition and
verification of the overall system performance and functionalities. Design of overall
transceivers for telecommunications, control, signal processing and modelling.
Antennas design and development and related integration technologies:
Simulations, optimization, development and measurements of various types of antennas
and arrays in various geometries (planar, patch antennas, collinear), frequency bands
(L,S,X Ku band, multiband), and various technologies for integration (microstrip, 3D etc)
and applications (broadband, narrowband, smart antennas, reconfigurable). Design and
development of matching techniques and electronic steering along with beamformers and
phase shifting circuits. Development of relevant simulation tools (analytical modelling
and high performance algorithms for array modelling and simulations).
Telecommunications systems, Radars and satellite communications:
Development of design and development of application specific radars, design,
development and testing of digital telecommunication systems, software development for
the control of sensor network systems, compliance of avionics to satellite
telecommunications standardization (ARINC 741, 761), development of satellite
transceivers L-band (1-2 GHz) and air transferred sat CDMA terminal 2-8 Mb/s,
development of mobile telecom system to support multimedia services of HELLASSAT etc.
III. Remote Sensing Systems
While working in The Hellenic Navy research Center but also afterwards, I worked for the
design and development of prototype surveillance and signal transmission systems. During
my presence at NTUA I deal with a variety of topics in the remote sensing field especially
related to the inverse scattering problem and the propagation of electromagnetic waves from
hot thermal bodies.
IV. Biomedical Engineering
After obtaining the position of staff member in 1984 at the National Technical University of
Athens (the oldest Technological University in Greece), I realized the importance of applying
science and in particular the electromagnetic technology in Biomedical Engineering which was
starting to appear as an independent engineering and scientific field. The aspects of
biomedical engineering on which I have concentrated my effort during the last 23 years are:
- Hyperthermia as an adjuvant therapy of some Cancer types in conjunction with
Radiation Therapy has been an important topic that has received international attention
during the last 20 years. Various disciplines such as electromagnetic and thermal
modelling of the human body, design of novel radiators and control systems are involved
in developing hyperthermia systems to be used in medical clinics. In the framework of
this research, extensive work has been carried out in modelling the interaction between
the human body and electromagnetic waves, as well as in designing and developing new
hyperthermia devices that have been used in several European Clinics (Greece and
Germany). Direct involvement with clinical research verified my deep belief that
“Fundamental scientific questions arise if one is involved in experimental and theoretical
research in parallel”.

- Brain Research. Extensive study of Event Related Potentials using signal processing,
inverse methods and Microwave Radiometry. Imaging and reconstruction of evoked brain
potentials: real-time evoked potential tomographic system
- Inverse scattering problem: Focusing on the task to develop an acoustic of
microwave technology mammography system, various methods based on Diffraction
Tomography were developed. An extensive work program in examining various
alternative inverse scattering methods has been implemented.
- Biophysical modelling of human cancer incorporating a wide spectrum of data
including medical images, biochemical, protein and gene expression data, as well as
pathologoanatomical data. The principal aim is to develop in-silico oncology methods.
- Biological tissue imaging using non-ionizing radiation: development of diffraction
tomography systems, microwave radiometry, imaging of excitable tissues in the human
brain
- Medical image processing and techniques: segmentation and reconstruction of
various medical data
VI. Optical Systems
In the framework of my work using optical methods in telecommunications I was involved
with the analysis of complex structures i.e. couplers, non linear optical waveguides,
propagation in dielectric materials and structures etc. Development of optical transmitters
and receivers, and optical connections for both analog and digital signals. Design of new
optical circuits, fiber waveguides, and Gbit/s electronic circuits
Involvement in Research projects
During the last two decades (1988-2008) I have pursued research programs in the following
fields:
- Design and development of microwave circuits and systems. Various
telecommunication modems used in satellite and terrestrial communications have
been developed starting from concept and up to test and evaluation.
- Design and development of high speed electronic circuits (analog and digital) in fiber
optic transceivers.
- Design and development of new-type coherent radar systems as sensors in
applications such as:
• Detection of trapped people in demolished buildings after an earthquake
• Anti-stealth radars to detect targets of very small echo
• Detection of leaks in underground pipes
• Ground penetrating high resolution image radar
• Navigation in three dimensional space with high accuracy
• Multi static radars
- High speed digital signal processing circuits including A/D converters, FFT based on
FPGA architectures
- Development of various types of new antennas operating from extremely low up to
millimeter wavelength circuits
- Development of biosensors for prevention of fatigue-caused driving accidents
- Learning technology tools incorporating sensors, data acquisition and internet
technology tools

- High Power Microwaves
All the above mentioned research was carried out by Ph.D. students under my supervision.
The number of graduate students that have obtained their Ph.D. under my
supervision is 65 during the last 30 years, more than 20 of whom have subsequently
followed successful careers in academia, both in Greece and abroad. Several of my former
students hold important positions in research institutes, companies and public bodies,
whereas some have established their own spin-off companies.
The primary source of funding of the aforementioned research has been the European
Commission, starting from 1983. Also some funding has been received from domestic
foundations and industry.
During my career he has administered research on various levels such as from the position of
Dean of School of Electrical and Computer Engineering (6 years), the founding Director of the
Institute of Communication and Computer Systems (8 years), which achieved being among
the leading contributors of the European Research Programs the last 10 years.
