Propagation of Microwaves in Magnetized Plasma and Air-Based Ternary Structure

Abstract

Using the transfer matrix method, the transmission spectra of magnetized cold plasma and air-based ternary photonic crystal, in microwave region, are investigated. Here, we analyze the impact of parameters, such as air thickness and angle of incidence, for fixed values of applied magnetic field and electron density, on the transmittance of the ternary PPC. Here, we find an enhancement in PBG at a comparatively lowe air thickness for normal incidence. Further, by varying the incident angle and kee** the air thickness fixed, we find that, there is broadening in the reflection band, where we get a large number of sharp transmission peaks at incident angle nearly 89° exhibiting the characteristics of multichannel filters. Wherefore, these two parameters, air thickness and incident angle, act as controlling factors for such a ternary periodic structure, and the novel features of the PC properties can be applied in designing microwave mirrors, multichannel filters, and optical switches. The insights of this analysis can further be utilized in designing some other related devices in a desired GHz frequency range.
