Nonlinear effects in high-power applications of metamaterials

Summary form only given. Metamaterials are artificial assemblies of multiple structures arranged in periodic patterns, designed to have electromagnetic properties that are not found in nature, such as negative refractive index, permittivity or permeability. Such properties enable a number of novel applications such as cloaking and can be utilized to reduce physical size or enhance operation of well-studied devices such as lenses, antennas and phase shifters.
