Using the transfer matrix method, the effect of temperature on thetransmission spectra of thermal tunable nano metallic photonic crystal filter has beeninvestigated. Three different materials H (high refractive index material), L (lowrefractive index material) and M as a metallic layer, have been used to make thisstructure. M layer is considered to be Silver. The complex refractive index of Sil...
