Abstract

A magnet-less nonreciprocal metasurface (MNMs) exhibiting enhanced transmission is presented. The metasurface is constituted of a 2D periodic array of a stacked annular pair of slots loaded with semiconductor-based unidirectional components sandwiching a dielectric slab spacer. The reflection and transmission dyadics of the metamaterial structure are computed using transmission line modeling with single-layer annular slot impedance dyadic. A parametric study is conducted in terms of the spacer permittivity and thickness to achieve enhanced transmission. Possibility of designing total transmission or total reflection magnet-less nonreciprocal metasurfaces is discussed.
