Usually with Photonic band structure, and contains in particular the periodic dielectric structures of Photonic band gap called Photonic crystals, theory and application of Photonic crystals in the past couple of decades have made great progress. In the latest research in Photonic crystals, Dirac geometry and singularity of new properties has become very popular. This procedure describes the scattering matrix method and transfer matrix method, and then briefly introduced the surface Plasmon polaritons and using transfer matrix method to calculate the dispersion relation of a typical. Then on dielectric slab waveguide mode to calculate the dispersion relation, discusses its TM model respectively. This paper calculates the energy flow by Poynting vector, using energy flow density defined transmittance and reflectance and transmittance and reflectance of the laminate are calculated. For one-dimension Photonic crystals using transfer matrix method to calculate the energy band struct
