Beautiful simulation Yuriy.

Hi Doug,
Yes, there is proximity as well as skin effects on the planes - the area
where signal power flow is shrinking with the frequency and current flowing
in thinner and thinner surface layer (result of absorption by the metal).
And all signal power is in dielectric and air! :)
See illustrations for microstrips at
https://www.simberian.com/ScreenCasts.php?id=38 and in some other
demo-videos at https://www.simberian.com/ScreenCasts.php?view=table or at

Best regards,
Yuriy

Subject: [SI-LIST] Skin effect on ground plane?
We all know what the skin effect is on a trace. And we all know the
return signal path is on the plane directly under the trace.
The question is, is there a corresponding skin effect on the ground plane?
