Abstract
The Fano resonance and EIR properties in different topological one-dimensional superconductor photonic crystals has been investigated theoretically using the Transfer Matrix Method (TMM). Different types of periodic heterostructures are studied and they are designed by alternating pairs of superconductor materials such (Nb/BSCCO), (Rb3C60/ YBa2Cu3O7) and (K3C60/(BiPb)2Sr2Ca2Cu3Oy). All artificial periodic structures are sacked by dielectric cap layer at different induced fields. To exam the efficiency of the reported structures, different parameters are used for analysis such as layers thicknesses, temperature, angle of incidence, the kind of superconductor materials and the dielectric constant of the cap layer. The investigation results exhibit the presence of tunable Fano resonances and EIR resonance peak accompanied by asymmetrical line shape and they are very sensitive to the dielectric cap layer, the superconductor materials and the wave incidence angle.

Summary
Photonic crystals (PCs) are the objects of various theoretical and experimental researches due to their ability to control the flow of electromagnetic waves (EMWs) Such microstructures open promising applications in modern optics[1,2,3] such as optical sensor[4,5,6], laser LEDs7, optical microcavities[8], salinity[9]. These photonic band gap (PBG) materials with a periodic dielectric profile can be found in (1D), (2D) or (3D) dimension depending on kind of periodicity along the coordinate axes. Effect of the dielectric thickness, wave incidence angle, Materials Research temperature degree, refractive index of dielectric cap layer and the principles of optical resonance are discussed
