Query: Complex waveguide based on a magneto-optic layer and a dielectric
  photonic crystal   We theoretically investigate the dispersion and polarization properties of
the electromagnetic waves in a multi-layered structure composed of a
magneto-optic waveguide on dielectric substrate covered by one-dimensional
dielectric photonic crystal. The numerical analysis of such a complex structure
shows polarization filtration of TE- and TM-modes depending on geometrical
parameters of the waveguide and photonic crystal. We consider different regimes
of the modes propagation inside such a structure: when guiding modes propagate
inside the magnetic film and decay in the photonic crystal; when they propagate
in both magnetic film and photonic crystal.
