Paper Abstract

The nonlinear electromagnetic response is one of the foundations of modern technology and it arises in natural materials at the atomic scale. We briefly present some of the fundamentals of nonlinearity in natural materials and then we present experimental studies of analogous behavior in meta-atoms, the fundamental building block of metamaterials. Specifically tunnel-diode loaded, microwave split-ring resonators are shown to enable various nonlinear phenomena including self-sustained oscillation, harmonic/comb generation, frequency locking/pulling, and quasi-chaos generation. We discuss the possible adaptation of these unit cells to create bulk nonlinear metamaterials.
