Abstract In this paper, we propose to use the Weyl semimetal- Co3Sn2S2 embedded between two Bragg reflectors attain Faraday rotation without an external magnetic field in mid-infrared region. Our results show high optical transmittance peak of 60% and a corresponding angle approximately − 34˚ over wavelength spectrum 7000–8000 nm. The increased originated through localization light inside defect layer. We also explore how ambient temperature affects transmission intensity angle, revealing that both can be modulated by temperature-dependent conductivity semimetal. Furthermore, impact varying thicknesses on is investigated. It observed that, with increase Co3Sn2S2, decreases while increases. Lastly, influence number layers response leads reduction augmentation which shifts towards shorter wavelengths.
