Abstract :
Self-collimation characteristics of the two dimensional metallic photonic crystals are studied for the TM and TE polarizations, respectively. The Drude dispersion model is adopted to describe the metal and the self-collimation behaviors for the TM and TE light beams along different directions are obtained for the near-infrared light waves. And a polarization beam splitter based on above structure is designed, which can avoid the output light propagating direction is influenced by the alteration of the incident direction of light beam within a certain region.
