Abstract: Composite material, devices incorporating the composite material and methods of forming the composite material are provided. The composite material includes interstitial material that has at least one of a select relative permittivity property value and a select relative permeability property value. The composite material further includes inclusion material within the interstitial material. The inclusion material has at least one of a select relative permeability property value and a select relative permittivity property value. The select relative permeability and permittivity property values of the interstitial and the inclusion materials are selected so that the effective intrinsic impedance of the interstitial and the inclusion material match the intrinsic impedance of air. Devices made from the composite include metamaterial and/or metamaterial-inspired (e.g. near-field LC-type parasitic) substrates and/or lenses, front-end protection, stealth absorbers, filters and mixers. Beyond the intrinsic, applications include miniature antenna and antenna arrays, directed energy weapons, EMI filters, RF and optical circuit components, among others.
