Abstract

We introduce the concept of nonreciprocal metagratings. We study surfaces that can enable nonreciprocal energy transfer between multiple Floquet channels. These surfaces are fully periodic arrays of nonreciprocal bianisotropic particles that can enable nonreciprocal wave manipulation with unitary efficiency. Notably, we study metagratings with bianisotropic moving particles as their building blocks. These bianisotropic particles are in fact stationary, however from electromagnetic point of view they emulate the characteristics of a real moving particles. As a possible application, we derive the required electric, magnetic, and electromagnetic polarizabilities of the bianisotropic moving particles for a metagrating capable of nonreciprocal space wave circulation with unitary efficiency.
