Semi-Analytical Approach for Scattering, Guidance, and Radiation in Two-Dimensional Photonic Crystals

摘要

An accurate semi-analytical approach for modeling electromagnetic scattering, guidance, and radiation by photonic crystals consisting of layered parallel-arrays or crossed-arrays of circular cylinders is discussed, using the lattice sums technique, the T-matrix algorithm, and the generalized reflection and transmission matrices for a layered system. The method is quite general and applies to various configurations of photonic crystals formed by a lattice of circular cylinders.
