Abstract

In this study, we present the theoretical investigations on transmission characteristics of quasi-periodic one-dimensional photonic crystals made by arranging dielectric and superconductor layers in Fibonacci and Octonacci sequences. The temperature-dependent dielectric constant of the superconductor has been calculated using Gorter–Casimir two-fluid model and transfer matrix method (TMM) is adopted for the analysis of propagation of electromagnetic wave through the photonic crystal structure. The transmission properties of the superconductor–dielectric photonic crystal (SDPC) can be tuned, since its response to electromagnetic wave depends on the London penetration depth, which is a function of temperature and magnetic field. The cut-off frequency was found to vary with temperature, angle of incidence, sequence generation number, and thicknesses of dielectric and superconductor layers.
