Ultrashort pulse decomposition in the turn of a meander microstrip line with a passive conductor

Abstract

The paper presents the results of evaluating the effect of changing the cross-section parameters of a meander microstrip line (MSL) with a passive conductor on the ultrashort pulse (USP) waveform and amplitude. The study revealed the occurrence of additional pulses in the structure under investigation in addition to cross-talk and main mode pulses. The delays of each pulse were determined and the conditions for USP decomposition in a meander MSL with a passive conductor into a sequence of seven pulses were formulated. By means of heuristic search optimization according to the criteria for fulfilling formulated conditions and the criterion of the minimum amplitude, we obtained the optimal parameters of the line cross-section, at which the USP is decomposed into a sequence of seven pulses with attenuation of 5.38 times relative to half of the electromotive force.
