New regions of diffraction reflection in apodized one-dimensional photonic crystals with a large modulation depth

Abstract

Particular features of the band structure of one-dimensional apodized photonic crystals based on metamaterials are studied in the case in which the medium is simultaneously inhomogeneous with respect to both the dielectric and the magnetic properties. It is shown that in the case of oblique incidence of light at large values of the modulation depth, a new region of diffraction reflection appears. This new region of diffraction reflection is also observed at magnetic permeability μ = const = 1. The particular features of the absorption and localization of light in these structures are examined.
