Bounds on metamaterials in scattering and antenna problems

Sohl, Christian LU ; Gustafsson, Mats LU and Kristensson, Gerhard LU (2007) European Conference on Antennas and Propagation (EuCAP) 2007 p.1-4
Abstract
This paper reports on physical limitations on metamaterials in scattering and antenna problems. A dispersion relation for the extinction cross section is derived from the holomorphic properties of the forward scattering dyadic. The result states that for a given volume, there is only a limited amount of scattering

and absorption available in the entire frequency range. The dispersion relation is verified numerically for the perfectly conducting circular disk, and theoretical bounds are illustrated for a plasmonic stratified sphere.
