摘要: The dispersion relation, the field distribution, and lifetime of radiational eigenmodes in two-dimensional photonic crystals composed metallic cylinders were calculated for E polarization by means numerical simulation dipole radiation based on finite-difference time-domain (FDTD) method. convergence central processing unit time compared with plane-wave expansion opaque frequency ranges transmission spectra method Pendry MacKinnon corresponded quite well to band gaps antisymmetric modes found diagram. relation symmetry obtained calculation consistent prediction group theory analytical expression long-wavelength approximation.
