| Abstract: | We show theoretically that the frequency range of photonic band gap of a hetero-structure which is made of a metallic photonic
and superconducting photonic crystal can be enlarged due to the combination of the reflection band properties of the superconductor–dielectric
(PC1) and metallic–dielectric (PC2) periodic structures. The transmittance and band structure of the considered structures
are calculated using simple transfer matrix method and the Bloch theorem. Beside this, we have also calculated the transmittance
of the superconducting photonic structure (PC1), metallic photonic structure (PC2) and heterostructure of metallic photonic
and superconductor photonic crystals (PC1/PC2) for TE and TM-mode at the different angles of incidence. |
