Magnetic photonic crystals, containing magnetic materials, have gained global attention due to their unique magneto-optical properties in the microwave frequency range. These structures can be tuned and controlled using external magnetic fields and temperature, allowing for PBGs in the desired frequency spectrum and specific width. Ferrites, or ferri-magnetic nonconducting oxides, are highly resistive and have lower conductivity than metals, making them suitable for tunable microwave devices, designing ferromagnetic amplifiers, using tunable filters, oscillators, bubble-storage memory, isolators, tunable lenses, active magneto-optics, and ferrite-loaded waveguides. Magneto-photonics has gained significant interest among researchers over the past few decades. These structures explore the magneto-optical effect and various properties of electromagnetic waves on the interface of magnetized ferrite-based photonic crystals. These structures work in microwave and terahertz regions and can be tailored for highly tunable dispersion, slowing down light waves in a controllable manner. The permeability of ferrites is strongly dependent on the applied magnetic field and temperature, allowing for novel tuning of photonic bandgaps with applied magnetic fields and temperature. The properties of dispersion, confinement properties of arising modes near the interface of magnetic photonic crystals, group velocity, phase velocity, and energy carried by them will be explored in sensors, waveguides, and enhancement of surface non-linear dynamics and effects.
