  3. Abstract:
  4. Diffraction of electromagnetic waves by a media containing periodic changes of characteristics is widely used in many optical devices and processing methods. Usually diffractive structures contain periodic changes of relative electric permittivity. In this article, we have analyzed electromagnetic wave interaction with a media containing periodic changes of both relative electric permittivity, and relative magnetic permeability. Most of this work is based on using transfer matrix approach and rigorous coupled wave method for analysis of both TE and TM polarizations. Our analytical formulation proves the possibility of polarization insensitivity in diffractive behavior of these structures under specific relationship between harmonic contents of electric permittivity and magnetic permeability
