eigenmode solver
Guys,
Does anyone knows about the limits and inaccuracies of the MW$ 4 eigenmode solver and the modal analysis follow up? I have tried a number of times with no luck whatsoever to analyze a Dielectric Resonator inside a WG and the results are TOTALLY wrong. Tried like 20 setups, increasing the mesh and all tricks and it failed to give the expected results again and again. I even tried the Time Dimain solver with some sort of dumping and I can see some indications about what I must see but still some 300% difference. I have designed that by HFSS and results were good -to-excellent. I have compared the first 10 modes inside and found increasing divergence between HFSS and MW$ after the 4-th mode.
I am not really sure which part of MW$ is not working properly - the eigenmode solver or the Modal analysis, but that program seem to fail badly with that structure.
I may even try to do the Modal analysis myself (if I have time) with the Eigenmode data of MW$ and compare. With HFSS (Fast sweep) it is just a breeze.
I will appreciate if you have managed to simulate successfully similar devices and/or can share experience inhere.

cheng
