Maximization of duration of ultrashort pulse that is completely decomposed in multiconductor modal filters

Paper considers improvement of the protection against ultrashort pulses by means of optimization of parameters of multiconductor microstrip lines. We have obtained three-, four- and five-conductor strip lines which will help to maximize duration of a pulse that will be totally decomposed in these structures. It was achieved by means of equalization of time intervals between decomposition pulses. The maximum amplitudes of the decomposition pulses were 2,2; 2,3 and 3,9 times less than the pulse at the near end of the line. 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 duration of a decomposed pulse.
