Abstract
The permittivity, permeability, and tangent loss of high magneto-optical mediums are controlled and modified in this manuscript. The paramagnetism and diamagnetism are controlled by the changing of strength and phases of the coupled driving fields. In addition, the study of the electric and magnetic tangent loss involves varying the phases of the control fields. The highest positive as well as negative group index is calculated to be ng=±2×107. The propagation of light in the medium corresponds to superluminal and subluminal characteristics by the positive and negative group indices. The maximum envelope of the wave (vg) is investigated to be vg=±15m/s. Reflection and transmission pulse intensity are also studied in the corresponding medium. The reflected and transmitted pulses show bright soliton behavior with time and space variation. The reflection and transmission pulse intensity are soliton-like behaviors around the origin of space and time coordinates. Dirac delta function types, pulses, shapes of reflection, and transmission are investigated, having small shifts and spread along space coordinates. The results demonstrate significant applications in optical communications, soliton radar technology, imaging, and time cloak technologies. The soliton-like behavior enhances target recognition and signal clarity, which benefits radar systems. Solitons in optical communication prevent signal loss for longer transmissions with more capacity. Stable soliton propagation reduces blur in imaging, improving image quality and diagnostic precision.
