Multivariate Analysis of Multiconductor Transmission Lines for Triple Modal Reservation

This article considers two structures of multiconductor transmission lines (MCTL) for triple modal reservation: with a reference conductor in the center and in the form of side polygons. The results of calculating the time and frequency responses of the MCTL in the range of parameters are presented. The calculation of the time response was carried out under various excitations: a trapezoidal pulse signal, electrostatic discharge and a signal from a real ultrashort pulse generator. As a result, deviations for the output waveforms and maximum voltage values were obtained, and a brief analysis of the bandwidth and frequency of the first resonance was performed. By means of parametric optimization of the MCTL by heuristic search, it was possible to reduce the output voltage (from 0.243 V to 0.235 V with an EMF of 1 V) and equalize the time intervals between the decomposition pulses.
