Analysis of 1-D magnetized plasma photonic crystal band gap characteristic for variable plasma parameters

Abstract

In this paper, comparative study of the binary and ternary magnetized Plasma Photonic crystal (PPC) using 1-D theoretical analysis has been presented. In PPC, plasma layers are periodically structured with dielectric medium, where wave propagation depends on effective plasma frequency (EPF). The EPF is lowest frequency which can pass through the PPC structure. The presence of plasma layer in PPC provides wide tunability of EPF and that enables to tune the PPC electronically for desired photonic band gap (PBG) in very fast manner by varying magnetic field, electronic concentration and thickness of plasma layer. Here, tunability of EPF for both binary and ternary PPCs has been investigated for different plasma parameters and presented in comparative manner. The value of EPF is lower for a ternary PPC as compared to the binary PPC and this difference could be more significant when more number of layers is structured. This property can be utilized for the design of filters in the range of UHF, SHF and EHF band and the study is very useful in this respect.
