Comparison of differential and common mode response for short transmission line using PEEC models

In this paper the common and differential mode responses are compared for three different circuit models for a short transmission line to a fast rising input signal. The three models are a the conventional method of characteristics model, a (Lp, P) PEEC model without delays as well as a (Lp, P, τ) PEEC model with delays. All three models give reasonable responses for the differential mode while for the common mode only the (Lp, P, τ) PEEC leads to acceptable answers.
