Abstract

We present the transmittance of two types of one-dimensional periodic structures as functions of the frequency of the electromagnetic field incident on them for different thicknesses of the layers from which they are formed. The first type of structure consists of alternating layers of a dielectric material and a lossy metal that is defined by the Drude model. The second type of structure consists of alternating layers of a dielectric material and a superconductor whose dielectric properties are described by the two-fluid model. The variance of the intensity and the bandwidth of the transmittance are strongly dependent on the thicknesses, temperature and frequencies. We have compared between the transmittance spectra and present some details about the two types of structure.
