چکیده
An accurate semi-analytical approach for modeling electromagnetic scattering and guidance by photonic crystals formed by layered parallel-arrays or crossed-arrays of circular cylinders is presented , 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 consisting a lattice of circular cylinders. The unit cell of array can contain two or more circular cylinders, which may be dielectric, conductor, gyrotropic med ium, or their mixture with different sizes. The periodic spacing of cylinders along each array plane should be same over all layers, otherwise the cylinders in different layers may be different in material properties and dimensions.
