Computational Electromagnetics<br />
Summary<br />
This 3-day course teaches the basics of CEM with<br />
electromagnetics review and application examples.<br />
Fundamental concepts in the solution of EM radiation<br />
and scattering problems are presented. Emphasis is<br />
on applying computational methods to practical<br />
applications. You will develop a working knowledge of<br />
popular methods such as the FEM, MOM, FDTD, FIT,<br />
and TLM including asymptotic and hybrid methods.<br />
Students will then be able to identify the most relevant<br />
CEM method for various applications, avoid common<br />
user pitfalls, understand model validation and correctly<br />
interpret results. Students are<br />
encouraged to bring their laptop to<br />
work examples using the provided<br />
FEKO Lite code. You will learn the<br />
importance of model development<br />
and meshing, post-processing for<br />
scientific visualization and<br />
presentation of results. Participants<br />
will receive a complete set of notes, a copy of FEKO<br />
and textbook, CEM for RF and Microwave<br />
<strong>Engineering</strong>.<br />
Instructor<br />
Dr. Keefe Coburn is a senior design engineer with<br />
the U.S. Army Research Laboratory.<br />
He has a Bachelor's degree in Physics<br />
from the VA Polytechnic Institute with<br />
Masters and Doctoral Degrees from<br />
the George Washington University. In<br />
his job at the Army Research Lab, he<br />
applies CEM tools for antenna design,<br />
system integration and system performance analysis.<br />
He teaches graduate courses at the Catholic University<br />
of America in antenna theory and remote sensing. He<br />
is a member of the IEEE, the Applied Computational<br />
Electromagnetics Society (ACES), the Union of Radio<br />
Scientists and Sigma Xi. He serves on the<br />
Configuration Control Board for the Army developed<br />
GEMACS CEM code and the ACES Board of Directors.<br />
What You Will Learn<br />
• A review of electromagnetic, antenna and scattering<br />
theory with modern application examples.<br />
• An overview of popular CEM methods with<br />
commercial codes as examples.<br />
• Tutorials for numerical algorithms.<br />
• Hands-on experience with FEKO Lite to demonstrate<br />
wire antennas, modeling guidelines and common<br />
user pitfalls.<br />
• An understanding of the latest developments in CEM,<br />
hybrid methods and High Performance Computing.<br />
From this course you will obtain the knowledge<br />
required to become a more expert user. You will<br />
gain exposure to popular CEM codes and learn<br />
how to choose the best tool for specific<br />
applications. You will be better prepared to<br />
interact meaningfully with colleagues, evaluate<br />
CEM accuracy for practical applications, and<br />
understand the literature.<br />
