Influence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals

In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...

Investigating the Longitudinal Optical Conductivity in Three-Layer Graphene Systems with Composes Mono-Bi-Bi and Bi-Mono-Bi and Bi-Bi-Mono

The longitudinal optical conductivity is the most important property for graphene-baseddevices. So investigating this property for spatially separated few-layer graphene systems analytically and numerically is the main purpose of our study. Each layer can be mono- or bi-layer graphene. The density-density correlation function has been screened by the dielectric function using the random p...
