Nonreciprocity: Nonreciprocal Magnetic Coupling Using Nonlinear Meta‐Atoms (Adv. Sci. 19/2020)

In article number 2001443, Stephan W. Anderson, Xin Zhang, and co-workers demonstrate a nonreciprocal system based on the linear and nonlinear meta-atoms. Theoretical studies and experiments reveal the bounds of the nonreciprocity based on the passive and nonlinear resonators. The paradigm may be employed to construct magnetless radiofrequency isolators and other nonreciprocal...
