Hello, I am Junseob Kim, MS student of Electrical Engineering in Texas A&M University. I am a beginner of comsol multiphisics and trying to solve a simple problem.
When electric wave exp(-jkz) with f=300mHz propagates to a box with permittivity Er=3 and length of 2lambda, I have to get a result of current distribution around the box. I could get a result of electric fields with a guide of Radar Cross Section but It is difficult to get a result of current distribution for me.
So, please let me know how to solve this problem. It would be helpful to me. Thank you very much.
