Dear sir/Madam,
I simulated by Emds simulator a RF package getting no good results in terms of loss. To solve my problem, I simulated a simple structure with momentum and then by Emds getting different results. In particular I simulated a strip line on a single layer allumina, botton closed and top open (info substrate). I used from a side a single port (on the edgs of the structure) and the other side an internal port (in a point internal). I'm interested to re(1/Y11) and re(1/Y22). Well, when I simulate by momentum I found realistic value, While by EMDS I found results too high. Could you give me a solution to my problem?
best regards
