Gas sensing applications using magnetized cold plasma multilayers

Abstract In this paper, we theoretically propose a novel magnetic field-dependent sensor using omnidirectional magnetized cold plasma photonic crystal in one dimension for TE polarization. The structure consists of asymmetric two periodic arrays from and sample cavity layer. Between the arrays, is sandwiched between quartz layers. methodology proposed detector depends on appearance sensitive defect mode. results clear that mode frequency significantly refractive index sample, it extremely to incident angle changes, applied field, number density electrons, layer thickness. optimized has high sensitivity 15.14 GHz/RIU, quality-factor 527.32, figure merit 1066.20 RIU −1 , where means unit. So, can aid solving many challenges chemical environmental applications.
