Non-reciprocity using quadrature-phase time-varying slab resonators
Mahdi Chegnizadeh, Mohammad Memarian, Khashayar Mehrany
In this paper, it is shown that non-reciprocity can be observed in time-varying media without employing spatio-temporal modulated permittivities. We show that by using only two one…
