SPICE Models for one-conductor and three-conductor lines excited by a uniform plane wave

This paper presents SPICE models for one-conductor line over a ground plane and three-conductor lines excited by an incident uniform plane wave. The models can be used to predict the voltage and current response at the terminations of the conductors. They take into account the boundary conditions at the line ends and can thus be integrated into simulations for EMC analysis. A plane wave is represented in the form of a voltage source feeding the model. Model validation is applied in time and frequency domain. The results are compared to a SPICE model from another source and a numerical simulation. Very good agreement can be observed.
