Fast coupling estimation in PCB environment

The paper presents an implementation of a multidisciplinary method of estimating the time domain and frequency domain crosstalk (coupling) between several adjacent transmission lines. The method is applicable for PCB configurations including microstrip and stripline. The method also handles some elementary configurations, such as: two wires over ground plane, ribbon, wires in a circular shield, etc. An experiment, conducted with a microstrip configuration, is presented, verifying the accuracy of the model over a wide frequency range.
