Transmittance spectra of photonic crystals with semiconductor, superconductor and graphene components

Resumen

Using the transfer matrix method, the transmittance in one dimensional (1D) photonic crystals composed of superconductor (HgBa2Ca2Cu3O8+δ), semiconductor (Gallium Arsenide, GaAs) and graphene materials was studied. Specifically, the influence of graphene on the transmittance spectrum was analyzed. In the theoretical calculations, the photonic crystal structure was modeled as a superconductor-block crystal, where the block consisted of a sequence of semiconductor layers interspersed with graphene sheets, which were theoretically treated as an effective medium. The transfer matrix method was used to calculate the transmittance of various structures, considering electromagnetic waves with TE polarization.
