The University of Pretoria has an extremely active (and large) research
group, and this year has provided 4 journal publications, with a further 4
accepted for publication later.
Much work is done on microwave antenna design and computational
electromagnetics.
Main contact details are Prof. Johan Joubert
(jjoubert@postino.up.ac.za), Prof Wimpie Odendaal
(wodendaa@postino.up.ac.za), Prof JAG Malherbe.
Stellenbosch also has an extremely active group, and this year has excelled
itself with 11 journal publications and 14 conference proceedings.
Main contact details are Prof J Cloete(jhcloete@sun.ac.za), Prof
David Davidson(davidson@sun.ac.za), Prof Howard
Reader(hcreader@sun.ac.za), Prof. Keith
Palmer(palmer@sun.ac.za), Prof Petrie Meyer (pmeyer@sun.ac.za).
The Computational Electromagnetics Research Group within the School of
Electrical and Information Engineering consists of Prof A.R.Clark
(a.clark@ee.wits.ac.za), and is mainly concerned with the
improvement of the theory behind the simulation package SuperNEC.
At present, I have work based on printed antennas, a hybrid FEM/MoM
implementation for dielectric patch antennas, and a microwave holography
map of the HartRAO Radio Telescope.
One of my new MSc's has attended a Satellite Course at Stellenbosh
University under the Sumbandilasat bursary scheme.
3 MSc's were produced in 2006.
Annual Reports of the group are compiled in September and are all to be
found on the sitewww.ee.wits.ac.za/~em, or
ytdp.ee.wits.ac.za/AnnualReport2006.html.
