Three-dimensional photonic metamaterials at optical frequencies.

Metamaterials are artificially structured media with unit cells much smaller than the wavelength of light. They have proved to possess novel electromagnetic properties, such as negative magnetic permeability and negative refractive index. This enables applications such as negative refraction, superlensing and invisibility cloaking. Although the physical properties can already be demonstrated in...

On three dimensional coupled bosons

In this work we study two complex scalar fields coupled through a quadratic interaction in 2 + 1 dimensions using the method of bilinears as suggested by Rajeev[8]. The resulting theory can be formulated as a classical theory. We study the linear approximation, and show that there is a possible bound state in a range of coupling constants.
