Abstract: | A novel formulation of radiation from a localized line source placed in two-dimensional photonic crystals consisting of layered
periodic arrays of parallel circular cylinders is presented. The method employs the spectral domain approach. The spectral
response of the photonic crystals to the line source excitation is calculated using the lattice sums, the T-matrix of a circular
cylinder, and the generalized reflection and transmission matrices of the layered system. The far-zone radiated field is obtained
using the conventional asymptotic method to the spectral response. The radiation patterns of the localized line source sandwiched
by two photonic crystals are numerically studied. |
