摘要
A tunable Janus absorptive frequency-selective reflector (AFSR) utilizing a graphene-based hyperbolic that showcases exceptional doubling octave frequency absorption (DOFA) or tripling octave frequency absorption (TOFA) is proposed. The multi-objective gray wolf optimization algorithm is employed to drive the transfer matrix method, optimizing parameters such as the dielectric permittivity, thickness, and the Fermi level (Ef) to achieve harmonic absorption. By manipulating the Ef of graphene, the dimensions of the absorption band and reflection window can be finely adjusted. Additionally, a frequency-selective reflector is introduced, enabling a seamless transition between selective absorption and transmission by adjusting the Ef. This AFSR represents a groundbreaking approach to achieving DOFA or TOFA while simultaneously offering valuable insights into the design of intelligent AFSRs.
