transient electromagnetic waves study

Please login with a confirmed email address before reporting spam

Hi,
I want to study the propagation of electromagnetic waves with time in a coaxial waveguide. What I want is at the beginning the wave is incident form the bottom of the waveguide and then propagating in the waveguide. I use the transient electromagnetic waves study and choose time dependent. But there is always error when computing. I can not figure out the reason. Attached is the model I made. Could any one please tell me where is wrong and how to fix it? Thank you!

Best,
Xinyu
