Stable time domain PEEC solution for pulse interconnection structures

Time domain methods for transient analysis of pulse excited interconnection structures are of big interest. Since frequency domain methods with IFT in a frequency range given by UWB pulses need much computation time, in particular, if system investigated have a low dissipation and the response time is relatively long in comparison with the exciting pulse. A further advantage of time domain methods is the opportunity for including non-linearities. Unfortunately, numerical time domain methods sometimes meet the problem of late time instability. This disadvantage holds also for the standard PEEC method and for MoM (MOT). The present paper provides a contribution for avoiding such instabilities. A modified full-wave PEEC method for obtaining stable time domain solutions is developed and tested.
