Semiclassical coupled wave theory for TM waves in one-dimensional photonic crystals.

Semiclassical coupled wave theory is extended to waves with the electric field polarized parallel to the plane of incidence (TM waves) in one-dimensional periodic dielectric structures. Using this theory, the bandwidths and reflection/transmission characteristics of such structures, as functions of the incident wave frequency, are in good agreement with exact numerical simulations even for very high refractive index contrast.
