摘要

This study investigates temperature-dependent plasmonic mode in chiroplasma–indium antimonide structure. Transfer matrix technique is utilized to obtain the characteristics equation. By using temperature-sensitive electromagnetic response of InSb and anisotropy of chiroplasma medium, characteristics equation is analyzed to explore the features of plasmon mode. Frequency dependent effective mode index (EMI), propagation length, and normalized propagation constant under different chirality, cyclotron frequency and InSb temperature are analyzed. Numerical results reveal that plasmonic modes exhibit strong dependency on mentioned materials parameters. The findings of this study will contribute to the advancement of thermos-optical sensors technology, detectors and surface waveguides in GHz frequency region.
