Research that falls under the Commission B ambit is mainly performed at the
major universities, and in associated research companies. Understandably,
it has actually
been quite difficult to gain co-operation from individual researchers in
the process of gathering information. As a direct result, only University
of Pretoria and the University of the Witwatersrand, Johannesburg, is
represented in the publications list.
1.1 Council for Scientific and Industrial Research
Dr Dirk Baker, Mr L.Botha lbotha@aerotek.csir.co.za
Prof J.Cloete , Prof D.Davidson and Prof H.C.Reader Keith
Palmer (antenna analysis and design) and Petrie Meyer (waveguide
propagation, filters) make up an active research group at Stellenbosch.
G.Smith agsmith@emss.co.za. Involved with FEKO development, FEKO is a
Finite Element based electromagnetics analysis package. Associated
to the University by the fact that most of his engineers hail from it.
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. I am currently supervising 4 postgraduates. Prof.
Fourie has now resigned, and is committed to Poynting Innovations on a full
time basis.
Also, Prof G.Gibbon g.gibbon@ee.wits.ac.za has some interesting work
in investigating the propagation of Electromagnetic fields that the
Elasmobranchii (eg sharks) are sensitive to in seawater (< 20Hz!).
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/AnnualReport2004.html.
Poynting Innovationswww.poynting.com is headed by Prof A.P.C.Fourie,
and has several active researchers in the fields of antenna design,
Electromagnetic analysis software (SuperNEC). SuperNEC is
a Method-of-Moments based package, and is continuously extended by research
efforts.
Since it has had historic ties with Wits, it still has a culture of
research, (as opposed to simple development). The main researchers are Dr
D.C.Nitch derek.nitch@poynting.co.za and Mr R.Dreyer
renier.dreyer@poynting.co.za. Most of the publications from Poynting
are captured on the Wits site.
Poynting Antennas is a World-class manufacturing plant, with heavy export
emphasis, from HF EW antennas to 6GHz WLAN dish feeds.
