Abstract: The absorption spectra of three-dimensional metal-dielectric photonic crystals are studied using computer simulation by the finite difference time domain (FDTD) method and the layered Korringa–Kohn–Rostoker method. The band structure of a three-dimensional dielectric PC is obtained by the plane wave expansion method. The explanation of absorption spectra of PC based on its comparison with the band structure and Fabry–Perot resonances inside a photonic crystal plate is given. The intensity distribution of an electric field using FDTD inside the metal-dielectric PC for three various structures is analyzed. It is shown that spherical cavities in a dielectric photonic crystal “focus” the field inside cavities at certain wavelengths. This leads to an increase of absorption at these wavelengths if metal spheres are located in the centers of those cavities.
