Brewster angle phenomenon in two-dimensional metallic photonic crystals and its application to polarization beam splitting
The authors show the Brewster angle phenomenon of p waves in two-dimensional metallic photonic crystals of rectangular lattices with effective medium theory and accurate multiple-scattering calculations. The Brewster angle can be tuned over a wide range by varying the structure parameters. Based on this phenomenon, the authors propose a polarization beam splitter which can completely separate the p and s waves at an incident angle of 45° ± 10° in a very wide wavelength range (1 ~ 500 μm).
