Tunable photonic band gaps in an extrinsic Octonacci magnetized cold plasma quasicrystal

In this paper, the characteristics matrix method is employed to theoretically investigate the propagation of electromagnetic waves through one-dimensional extrinsic Octonacci magnetized cold plasma (MCP) quasicrystal. Compared with the periodic structure, the results show that such type of structure has more numbers of photonic band gaps (PBGs) within the selected computational range. These PBGs can be easily manipulated by tuning the external magnetic field (B), electron density (ne) and the thickness ratio (ρ). When considering the case of B and ne, the analysis of the results shows that the pattern of change in the transmittance spectrum is opposite to each other. Moreover, the influence of the structural configuration of parameter ρ on PBGs is noteworthy and quite different from B and ne. The observed results are of technical use in the design of a multichannel microwave reflector.
