Negative refraction in three-dimensional point-dipolelike polaritonic crystals

A. Rose, K. Kempa
2010 Journal of Applied Physics  
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 crystals and show that they are capable of negative refraction, and can be constructed from available materials for experimental demonstrations
