Quasi-static and electrodynamic simulation of reflection symmetric modal filter time response on ultra-short pulse excitation

摘要

The article considers the protection of radio-electronic equipment against ultrashort pulses (USP) by means of modal filters (MFs). The reflection symmetric MF structure is analyzed. The results of a quasi-static and electrodynamic analysis of reflection symmetric MF under influence of the USP, without consideration and taking into account losses in conductors and dielectrics, are presented. The maximum deviation for output pulses during simulation using different methods was 5 % for amplitudes and 2.5 % for delays. The necessity of careful consideration of frequency dependence of parameters of the MF materials has been revealed.
