چکیده :
Breaking electromagnetic reciprocity enables the creation of photonic devices with asymmetric transmission and advanced functionalities. While magnetizing is a promising approach to achieve nonreciprocity, its impact is limited by the weak magneto-optical (MO) response of natural materials. Integrating epsilon-near-zero (ENZ) materials offers a powerful solution to address this challenge. A multilayered structure has been proposed in this study, combining magnetized ENZ materials with engineered asymmetry to achieve robust and broadband nonreciprocal optical transmission. Numerical investigations reveal giant enhancements in isolation performance, achieving isolation ratios exceeding -99 dB at a frequency of ω=0.253 (2πc/a), which has been improved nearly 5 times more than not utilizing ENZ. Also, the insertion loss has been decreased. This unprecedented result is attributed to the synergistic interplay between ENZ properties and magnetism, enabling suppressed forward wave propagation and enhanced backward wave transmission. These findings underscore the transformative potential of magnetized ENZ materials in developing next-generation nonreciprocal photonic devices, with significant implications for advanced optical and electromagnetic systems.
