Homogeneous RF electric field

Please login with a confirmed email address before reporting spam

Hey guys,

i hope anybody can help me!

My model is 2d rotationalsymmetric. I want to define a homogeneous RF electric field in z-direction inside a sphere. I use the electromagnetic waves-module in the RF-Physic and create a sphere, on which surface i defined user-defined ports. With this i get a homogeneous electric field in lower frequencies. When i simulate with radio frequencies, i get a inhomogeneous field. The problem might be a phase-shifting and interference. Has anyone a idea how to fix this problem?

Thx!
Konrad
