“…Under the magneto-optical effect, the one-dimensional (1-D) magnetized ferrite photonic crystals (MFPCs) have become the hot research issue due to their perfect magnetic tunability [1][2][3]. As the gyromagnetic dielectrics, the ferrite materials display the special permeability tensors under the transverse and longitudinal magnetization configurations [4,5], which bring about the splendid anisotropy and have the promising prospect in the manufacture of the optical filters [6,7], the waveguides [8,9], and the optical circulators [10,11]. Some experimental researches about the optical properties in the magnetically regulative photonic crystals (PCs) were also implemented [12,13].…”

Utilizing the transfer matrix method, a multifunctional infrared device possessing the properties of the wide-angle broadband absorption and the polarization separation based on the one-dimensional (1-D) magnetized ferrite photonic crystals (MFPCs) arranged by the Dodecanacci sequence is designed theoretically under the modulation of the external magnetic field. The magneto-optical effect generated in the proposed MFPCs gives birth to the ultra-broadband absorption regions under the transverse electric (TE) mode, one runs at 16.22 THz –30.89 THz and the other covers at 33.52 THz–70.00 THz. The mechanism of the wide-angle (at most 80.89° for TE mode) absorption is analyzed by the interference cancellation condition. Moreover, owing to the different effective permeabilities of the MFPCs under the two polarization modes, the propagation behaviors of the electromagnetic (EM) wave are diverse which present the absorption features under the TE mode and show the transmission properties under the transverse magnetic (TM) mode in the structure. Compared with the periodic and Thue-Morse structures, the complex symmetry of the Dodecanacci sequence makes the absorption features of the MFPCs superior to that of the former. Besides, the influences of the magnetic field intensity and the dielectrics’ thicknesses on the angle-insensitive absorption and polarization separation characteristics are discussed explicitly. This research provides meaningful guidance for the modulation and absorption of the infrared light wave and the design of the multifunctional magnetically tunable optoelectric device.
