imaginary wave impedance
Hi all,
I am trying (hard) to simulate planar inductor on silicon in MWS. After long I stick with the two following main problems:
Port definition : the substrate has a resitivity of about 1ohm.cm and I can have trouble to couple the energy correctly in the conductors most of the port energy being dissipated in the substrate. I tried to separate the ports from the lossy substrate bya piece of stripline but then I have a lot of reflections on the lossless/lossy interface and I have no idea how to match them.
Mesh problem : we use several thin layers, dielectric and magnetic and I think have to rely on the PBA even so I cant imagine how the reuslts would looks like
I have port memory exeption when I try to mesh the thin layers manually. By the way, did somebody models thin layer only with one cell, can he tells me the accuray he got?
after countless hours I still can't consider having consitent results even though I sometimes go correct results.
