Abstract
In this paper, we studied filtering properties of one-dimensional nanophotonic crystal with asymmetric geometry structure under irradiation Gaussian beam. By using the transfer matrix method and Two-Fluid model, we observed that nano layered structure containing superconductor can act as a multiple-channel filter. So that, number of resonant modes depend on designing filter (number of joint interference). We also investigated the effects of incident angle of Guassuain beam, radial coordinate of Gaussian beam (r) and the temperature on the filtering behavior of nano structure. For long Rayleigh ranges our results for the Gaussian beam were the same as that for plane wave. The proposed filter structure can be used in modern communication systems.
