Dear all,
I have a simple problem in HFSS which is that I cannot get the reflection coefficient from dielectric correctly on 30 GHz-->35 GHz frequency range. I have 2 layers, one of them is of relative permittivity 15 and the other layer is air. If a plane wave is incident from air region to hit the dielectric, The reflected amplitude divided by incident one should be easy to get. Using waveport on the top of air layer as a source and PML on all other faces didn't help me to get the expected (constant) plot with frequency. I attached the HFSS file just in case I didn't explain well. I didn't add any excitations or Boundaries since all seems wrong to me.
Thanks in advance
