Exciting coaxial cable in xfdtd

[micky74]

Hi, I faced a problem in exciting a coaxial cable in XFDTD. How do you excite this cable when you have an inner and outer conductor? I've tried to put a voltage source across it but result is funny. I'll appreciate it anyone can send me an example file on it.

Thanks in advance!

Hello Micky:

Can you post your cable's geometric parameter on the forum?
Also, do you know where people can find the cable geometric information and material information?
