In-depth analysis of hybrid SPP wave propagation at the Chiral–Graphene–Dielectric (CGD) interface is carried out. The single-layer graphene is modeled using Kubo formulism and the impedance matching boundary conditions are utilized to derive the dispersion relation. TM-TE decoupled modes at the CGD interface are shown. The effective mode index and propagation length of hybrid plasmon modes are found to be sensitive to chiral strength (ξ), chemical potential (μc), radius of waveguide, and refractive index of chiral (n_c). It is observed that the cutoff values of chiral strength and radius promote Goos–Henchen effect at CGD interface. The present work may have potential applications for on-chip optical, chiral sensing and enantiomeric detection and renewable energy technologies in the terahertz frequency regime.

对手性-石墨烯-电介质（CGD）界面上的混合SPP波传播进行了深入分析。使用久保公式对单层石墨烯进行建模，并利用阻抗匹配边界条件得出色散关系。显示了CGD接口处的TM-TE解耦模式。发现混合等离子体激元模式的有效模式指数和传播长度对手性强度（ξ），化学势（μc），波导半径和手性折射率（n _c）敏感。可以看出，手性强度和半径的截止值会促进CGD界面的Goos-Henchen效应。本工作可能在太赫兹频率范围内对片上光学，手性传感和对映体检测以及可再生能源技术具有潜在的应用。
