P3-36: Dispersion properties of plasma-filled two-dimensional metallic photonic crystals

摘要

The dispersion characteristics of two-dimensional (2D) plasma-filled metallic photonic crystals (PC) with square lattice are studied by the finite-difference time-domain (FDTD) method. The results show that the dispersion curves of TM and TE modes all move to higher frequency when the PC filled with plasma. Furthermore, a cut-off frequency appears in the first passing band of TE mode due to the existing of background plasma.
