Numerical analysis of absorptive two-dimensional metallo-dielectric photonic crystals

摘要

The effect of considering dissipation in the model for the metallic component of metallo-dielectric photonic crystals is studied. The study has been carried out with the Transfer-Matrix Method with the help of the TRANSLIGHT software package. The influence of the filling fraction and of the background dielectric constant on the width of the second band gap and on the cut-off frequency for E-polarization has been analyzed. The influence of different levels of dissipation on the transmittance and reflectance spectra and on the absorption has been calculated, with special attention to the absorption induced at the plasmonic resonances in H-polarization.
