PHOTONIC BAND STRUCTURE OF 1D PERIODIC COMPOSITE SYSTEM WITH LEFT HANDED AND RIGHT HANDED MATERIALS BY GREEN FUNCTION APPROACH

Abstract

In the framework of the Green function method, we theoretically study the photonic band structure of one-dimensional superlattice composed of alternating layers of right-handed and left- handed materials (RHM and LHM). The dispersion curves are studied by assuming that the dielectric permittivity and magnetic permeability are frequency dependent in each layer. It is shown that such structures can exhibit new types of electromagnetic modes and dispersion curves that do not exist in usual superlattices composed only of RHM.
