Rigorous dispersive analysis of skin effects on a printed microstrip line containing finite conductor losses

Theoretical full-wave analyses of skin effects on a microstrip line plated with 1 mil (1/1000 inch) thick gold conductor are presented. The time-harmonic complex longitudinal and transverse current distributions inside and on the surface of the metal strip are reported for a microstrip operating at 100 GHz. The case study shows that the current distributions obtained by the new full-wave approach agree well with those predicted by the well-known plane analysis of skin effects.
