title: Reciprocity between the effects of resonant scattering and enhanced radiated power by electrically small antennas in the presence of nested metamaterial shells.
abstract: Reciprocity between the power scattered by nested metamaterial shells and the power radiated by an antenna centered within those nested shells has been investigated. Resonant scattering caused by an incident, fundamental transverse-magnetic mode was found to be reciprocal to the power resonantly radiated by an electrically small electric dipole for a variety of configurations. These findings indicate that the power radiated by an electrically small antenna and scattered by an electrically small object can be significantly increased through the use of realizable metamaterials.
