摘要：A photonic crystal provides a possibility to control and manipulate the propagation of light. Many numerical methods have been used to study photonic crystal structures. Among them, comsol multiphysics have been used here to design photonic crystal structure. Also the study of TE and TM waves propagating through the crystal are considered. Electromagnetic waves incident onto such PCs from directions covering a wide range of incident angles become highly localized along a single array of rods, which results in the narrow-beam propagation without divergence.TheSelf-collimation is dispersion-related phenomenon, which possesses sufficient bandwidth to function as an effective waveguide mechanism through a substantial propagating distance.
