Anomalous Propagation in Photonic Crystals with Square Rods
正方介质柱光子晶体中异常传输现象研究

The propagation of electromagnetic wave was investigated in two-dimensional photonic crystals(PCs) which are formed by square dielectric rods arranged in a square lattice.Total reflection and complicated anomalous refractions,such as the self-collimating phenomenon and negative refraction,were found in the first partial band gap when the interface of the PCs is changed and the incident angles are different.The plane wave expansion method was used to calculate and analyze the photonic band structure as well ...
