Several examples were presented and
solved with the computer code FEKO,
demonstrating the successful application
of these techniques.

Marlize Schoeman received the B.Eng-M.
Sc.Eng and PhD degrees in Electronic and
Computer Engineering from the University of
Stellenbosch, South Africa, in 2003 and 2006,
respectively. There she has been involved with
research activities concerning computational
electromagnetics and rational function interpolation
and approximation techniques. Since
July 2006 she has been with EM Software &
Systems, Stellenbosch, South Africa, where she
is doing research and development on the kernel
of the FEKO code.
Ulrich Jakobus received the diploma, PhD
and Habilitation (venia legendi) degrees in
Electrical Engineering from the University of
Stuttgart, Germany, in 1991, 1994, and 1997,
respectively. There he has been actively involved
in research on numerical techniques for the solution
of electromagnetic problems with special
emphasis on EMC, and this research lead to the
computer code FEKO. Since October 2000 he
is with EM Software & Systems, Stellenbosch,
South Africa, with the roles of Director, FEKO
Product Manager, and team leader of the FEKO
kernel team. n
