Abstract

We discuss the use of non-linear effects in metamaterials to break time-reversal symmetry, allowing signal transmission from one direction to another, but not the other way around. Compared to other approaches for breaking reciprocity, non-linear metamaterials have the significant advantage of not relying on any form of external bias, and they can be used for the protection of sources or other sensitive equipment from strong external signals. We also discuss their implications in the context of self-induced topological protection.
