Negative refraction in three-dimensional point-dipolelike polaritonic crystals

Abstract

We propose two practical realizations of the point-dipole crystal, shown previously to be capable of negative refraction and other metamaterial and plasmonic properties. These are: an array of highly polarizable spheres, and the complementary array of spherical cavities in a highly polarizable medium. We study light propagation through these polaritonic… (More)
