Looks interesting. I might even be able to model yagi boom effects.

I tried the waveguide tutorial , but the matlab scripting front end
fails. The constant c0 ( speed of light) was missing and the FDTD line
borks.

??? Undefined function or method 'InitFDTD' for input arguments of type
'char'.

Error in == ems_waveguide at 41
FDTD = InitFDTD('NrTS',1e4, 'OverSampling', 5);

I'm running an old Matlab R2010b and I know later Matlab versions aren't
backward compatible.

Maybe Octave ( which is free) would be better. Upgrading Matlab is
expensive.


Apologies, didn't note the Matlab dependency.

Only use Matlab once when at Nokia to analyse the world-wide production
looking for bugs in the test software, Cpk, 6 sigma and all that.


I got it to run on Matlab. It was a path setting problem . RTFI
applies. ;-0

ran the waveguide and patch antenna tutorials ok, but the helical
antenna seems to be taking a while.

Cheers

Brian
