Non-reciprocal Bandpass Filters: Parametric Simulation

Non-reciprocal filters using time-varying transmission lines (TVTL) have recently gained prominence. The basis of their functionality lies in the time modulation of space-separated resonators using sinusoids having progressive phase shifts. The purpose of this paper is to mathematically simulate a bandpass filter exhibiting non-reciprocity at the center frequency deploying the concept of time-modulated transmission lines based on a published model and extend the analysis with a detailed parametric study of the competitors that delve towards the generation of non-reciprocity. The study dealt with is still obscure in the recent developments in this domain.
