Earning a doctoral degree
”Government Decree on University Degrees Section 22, (1) and (3):
To earn a degree of Doctor of Science, the student must:
1. complete the required postgraduate studies,
2. demonstrate independent and critical thinking in relation to their field of
research,
3. write a doctoral dissertation and defend it in public.
An approved doctoral dissertation may also be a monograph or a number of
scientific publications or manuscripts vetted for publication deemed
sufficient by the university, which deal with the same set of problems and a
paper summarising the findings or some other work which meets
corresponding scientific criteria. Publications may also include co-authored
publications if the author’s independent contribution to them can be
demonstrated.”

4. Write the thesis manuscript (a monograph or a summary of the
articles)
5. Apply for permission to publish (The appoinment of preliminary
examiners)
6. Reply the examiners’ comments and make the required revisions

Preliminary examination
▶ When your supervisor is happy with your manuscript, it can be
sent to pre-examination.
▶ (Before that, a language check is recommended.)
▶ ”The supervisor is responsible for finding suitable preliminary
examiners with expertise on the topic of the dissertation; they
must actively publish in the field of the dissertation. They cannot
work in a close relationship with the doctoral dissertation writer,
supervisor or instructor to avoid partiality concerns (as regards
partiality, the rules pertinent to opponents apply).”
▶ The examiners have 8 weeks to give their statement (In my
case, due to the summer holidays, the time was extended to
10(?) weeks)

My thesis
Complex Electromagnetic Responses from Simple Geometries
▶ Supervisor
Department of Radio Science and Engineering
▶
Prof. Ari Sihvola
▶ Instructor
▶ Dr. Henrik Wallén
How to solve the polarizability of a
hemisphere? What are surface plasmons, or
electrostatic resonances? Can a composite
slab be modeled as an effectively
homogeneous medium? How are its
effective material parameters then
retrieved, and what are the limitations of
this homogenization procedure? We find out
that even simple geometries can sometimes
behave in a complex way.

Väitöstiedote 22.11.2011
Muodoltaan yksinkertainen voi olla sähköisesti
monimutkainen
Väitöskirjan nimi
Väitöskirjan sisältö
Complex electromagnetic responses from simple geometries
Yksinkertaisten geometrioiden synnyttämät monimutkaiset sähkömagneettiset
vasteet
Jokainen väliaine tai materiaali kätkee sisälleen paljaalle silmälle näkymättömän
mikrotason hienorakenteen – viime kädessä alkuaineetkin rakentuvat omista
atomeistaan. Aineen sisäisten rakenneosien ja ulkoisten sähkö- ja
magneettikenttien monimutkaisen vuorovaikutuksen seurauksena määräytyvät
aineen havaittavat sähkömagneettiset ominaisuudet, joita usein voidaan kuvata
yksinkertaisilla makroskooppisilla parametreilla. Väitöskirjan tavoite on syventää
ymmärrystä materiaalien sähkömagneettisesta mallinnuksesta. Tulee siis pystyä
määrittämään aineen sisäisten rakenneosasten vaste, joka määräytyy pitkälti
näiden pienten rakennuspalikoiden muodosta.
Väitöskirjassa mallinnetaan erityisesti puolipallon muotoista kappaletta.
Erikoistapauksena tutkitaan tilannetta, jossa kappaleen sähköinen permittiivisyys on
negatiivinen ympäristöönsä nähden. Tällöin kappaleen pinnalle voi herätä hyvin
voimakkaita kenttämuotoja, ns. pintaplasmoneja. Erityisesti terävien nurkkien
havaitaan aiheuttavan hyvin voimakkaita vasteita.
Viime aikoina suurta kiinnostusta ovat herättäneet täysin keinotekoiset aineet, ns.
metamateriaalit, joille pyritään luomaan ominaisuuksia, joita ei luonnossa sinällään
esiinny. Väitöskirja perehtyy keinotekoisten materiaalien luomisen edellytyksiin ns.
homogenisointimenetelmien kautta ja etsii rajoituksia aineen rakennuspalikoiden, eli
ns. yksikkökoppien, vähimmäismäärälle ja maksimikoolle.

The defence
Mine took place on December 15, 2011
”The public examination
is an event where a doctoral student or candidate defends
the scientific findings presented in his/her dissertation.
In the event, the opponent presents questions, to which
the candidate responds. The opponent is usually holds
a doctorate or professorship in the field of the dissertation,
and the public examination is supervised by the custos,
usually the professor who has supervised the thesis work.”
Don’t forget the protocol!

Graduation
▶ The opponent gives a written statement on the thesis and the
defence and a proposal for a grade (Fail / Pass / Pass with
distinction)
▶ One more meeting of Doctoral Programme Commitee is needed
▶ Finally the degree is awarded by the dean
▶ In my case, DPC had one more additional meeting right before
Christmas, and I graduated on December 19, 2011
