Time domain analysis of skin effect on lossy interconnections

A new skin effect equivalent circuit has been presented in a previous work (1990) where the ground plane has been considered as a perfect conductor. In this letter, the loss due to the returning current in a resistive ground plane is accounted for. A modified skin effect equivalent circuit is presented and analysed by SPICE to obtain the propagation parameters as a function of frequency. This equivalent network is analysed in the time domain. Responses obtained have good agreement with those given by other methods.
