Optimization of parameters of multiconductor modal filters for protection against ultrashort pulses

Abstract

Paper considers improvement of the protection against ultrashort pulses by means of optimization of parameters of multiconductor microstrip lines by different criteria. We have obtained a three-conductor microstrip line with the maximized difference of delays between the first and the last decomposition pulses. It was achieved by means of expansion of time intervals between decomposition pulses. At the same time, signal amplitude at the output of a line considerably decreases (almost twice). The results have shown that it is important to optimize multiconductor modal filters considering both minimization of amplitude of an output signal and maximization of difference of delays between the first and the last decomposition pulses.
