Re: NEC-LIST: Supernec

Hi Doug

Regarding simulating loaded monopoles and dipoles, a SuperNEC user has
recently used the Genetic Algorithm optimizer in SuperNEC to optimize load
positions and values of a monopole. A short summarized version of the work
appears in our latest newsletter with a picture of the constructed monopole.
If you have not received our newsletter via e-mail you will find the
newsletter posted on our website in a few days.

The free version is fully capable except for a segment limit of 300, which
is more than sufficient for simulating most antenna types.

SuperNEC can be used either with Matlab or without. The advantage (and only
difference) of using SuperNEC with Matlab is that the user can write scripts
and programs to interface with SuperNEC, making it very powerful and
flexible. The engine is of course based in C++ and uses the optimized ATLAS
BLAS libraries.

I hope this clears up a few questions.

Renier Dreyer
