Analysis of optical cavities in the presence of negative refractive index materials

Abstract

We introduce the ABCD matrix for negative refractive materials (NRM) and investigate the optical properties of (NRM), according to the matrix method. The propagation of a Gaussian beam inside a NRM slab is also investigated. It is demonstrated that for n = −1, the waist of the transmitted Gaussian beam is the same as the waist of incident beam, which leads in the perfect lens. Further the optical resonator in the presence of NRM is studied and the stable condition is introduced.
