Dispersion characteristics of square and triangular metallic photonic crystals filling with plasma are investigated by finite difference time domain(FDTD) method.Effects on TM and TE modes in the two-structures with the variation of plasma density are analyzed.The results show that the dispersion curves of 2-D metallic photonic crystal filling with plasma upshift to the higher frequency .The width and location of bandgap of TM and TE modes can be controlled by the density of plasma.These properties of the 2-D Metallic Photonic crystal with background are potentially valuable in the aspect of designing tunable photonic crystal device.
