Comparative Analysis of Photonic Bandgap and Transmittance in ID Photonic Crystals

In this article, the variation of photonic bandgap and transmittance for one-dimensional dielectric periodic layered structure with angles of incidence have been studied. It gives the working of s-polarized electromagnetic wave, as tunable s-polarized filter, which stops the p-polarized wave. Two material structures Air/AgNO
₃
and Air/Pb
₂
O, have been studied. The transmittance in (Air/Pb
₂
O) has been found to be better. Transmission of the wave best appears at increase in incidence angle.
