▎ 摘　　要

A theoretical investigation has been carried out to find the reflection and transmission coefficient due to the interaction of electromagnetic waves with a chiral slab sandwiched between graphene layers. The reflection and transmission coefficients at graphene-chiral and chiral-graphene interfaces have been obtained analytically. Numerical results are presented to show the effect of the chirality, thickness of chiral slab and the normalized conductivity of graphene on the reflected and the transmitted powers.
