【 摘 要 】

The article presents the simulation of a modal filter with broad-side coupling, having a passive conductor in reference plane cutout. The authors calculate the matrices of per-unit-length parameters L and C and investigate the influence of end terminations of the passive conductor of the modal filter. As a result, we achieve alignment and minimization of the amplitudes of the decomposed pulses and show the possibility to attenuate the input ultrashort pulse with a duration of 450 ps 4.5 times.
