【 摘 要 】

This paper presents a theoretical investigation of electromagnetic wave coupling and tunneling through chiral-chiral interfaces. The dispersion relation, conditions of the trapped modes, and evanescent wave coupling and tunneling in an optically active chiral slab and chiral ambient medium are derived. The transfer matrix method is developed to obtain the transmission and reflection coefficients across the chiral slab. The formation of discrete trapped modes and the continuous interval, where the discrete trapped modes are embedded, are determined by the chirality parameter of the chiral slab. The instantaneous field components, revealed via evanescent wave coupling and tunneling through the chiral slab interfaces, are also reported.
