Summary:
This 3-day course teaches the basics of CEM with
application examples. Fundamental concepts in the solution of
EM radiation and scattering problems are presented. Emphasis
is on applying computational methods to practical applications.
You will develop a working knowledge of popular methods such
as the FEM, MOM, FDTD, FIT, and TLM including asymptotic
and hybrid methods. Students will then be able to identify the
most relevant CEM method for various applications, avoid
common user pitfalls, understand model validation and correctly
interpret results. Students are encouraged to bring their laptop to
work examples using the provided FEKO Lite code. You will
learn the importance of model development and meshing, post-
processing for scientific visualization and presentation of results.
Participants will receive a complete set of notes, a copy of FEKO
and textbook.
Instructor:
Dr. Keefe Coburn is a senior design engineer with the U.S.
Army Research Laboratory in Adelphi MD. He has a Bachelor's
degree in Physics from the VA Polytechnic Institute with Masters
and Doctoral Degrees from the George Washington University.
In his job at the Army Research Lab, he applies CEM tools for
antenna design, system integration and system performance
analysis. He teaches graduate courses at the Catholic University
of America in antenna and remote sensing. He is a member of
the IEEE, the Applied Computational Electromagnetics Society,
the Union of Radio Scientists and Sigma Xi. He serves on the
Configuration Control Board for the Army developed GEMACS
code and the ACES Board of Directors.
