Design of structural gigahertz multichanneled filter by using generalized Fibonacci superconducting photonic quasicrystals

Abstract

The design-properties of one-dimensional photonic quasicrystals (PQC)are studied in a microwave frequency range using the transfer matrix method (TMM)and Gorter Casimir Two-Fluid Model (GCTM). The PQC is constructed by a dielectric (SiO 2 )and High Tc superconducting BSCCO (Bi 2 Sr 2 CaCu 2 O 8 )materials and organized following the Generalized Fibonacci class (GFC). We have shown that similar channels with zero transmission easily controlled by the order and the lattice parameters of quasiperiodic systems. The cutoff frequency of the opened central gap found at specific arrangement (m = n)is adjusted with changing the temperature and layer thickness of superconductor. The main heterostructure can be useful to design a gigahertz multi channeled filter with similar channels.
