Multiphysics Sensor Based on the Nonreciprocal Evanescent Wave in the Magnetized Plasma Cylindrical Photonic Crystals

In this paper, a multiphysics quantity sensor is proposed based on a magnetized plasma cylindrical photonic crystals structure which is using the nonreciprocal evanescent wave principle. The sensor primarily consists of magnetized plasma and two isotropic dielectrics with a periodic asymmetric structure. Due to the introduction of evanescent waves, a sharp peak in the transmittance spectrum can be calculated by the transmission matrix method, relying on which physical quantities such as plasma density, incidence angle, magnetic induction strength, etc. can be attained, and the refractive index can also be derived after the addition of dielectrics in the structure. After adjustment, the sensitivity and quality factor values of these physical quantities at the forward and backward propagation of electromagnetic waves are
