Nonlinear and active RF metamaterial applications using embedded devices

摘要

Nonlinear metamaterials have received considerable attention in recent years. The inclusion of nonlinear andactive effects in metamaterials expands the possibilities for engineering media with designer properties. Wedetail our recent efforts to create nonlinear and active metamaterials at RF with useful properties throughthe inclusion of embedded nonlinear or active elements. We demonstrate some of the possible applications ofsuch nonlinear and active metamaterials experimentally, with properties including saturable absorption, phaseconjugation, and power harvesting.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
