Re: NEC-LIST: Coupling to short wires at low frequencies

I think it might present some problems, but if you get the source
code, I bet you can overcome them. If the limitation is simulation
technique (e.g., integration), then you can compensate. The best to
hope for is that ultimately the problem relates to available memory.
If you find this is the case, you can re-dimension the arrays, and
brute force the program into submission.

I recommend modifying the fortran source, rather than the f2c-ed
c-code source, but either is viable.

Subject: NEC-LIST: Coupling to short wires at low frequencies

I am calculating plane wave coupling to a network of wires with
NEC2. Some of the wires are only 1 meter long. I have to perform the
analysis over a range of frequencies, starting as low as 10 kHz.

My question is this: At 10 kHz, the 1 meter wires are much less than
1/1000 of a wavelength. The NEC manual states segment lengths of less
than 1/000 of a wavelength should be avoided. Will my analysis be
invalid for the 1 meter wires?
