Abstract

We present a theoretical study of Goos-Hänchen shift and associated time delay of a p-polarized electromagnetic wave packet for total internal reflection at a plane interface between two media of different permittivity, with graphene at their interface. The study is based on the energy-flux method which takes into account the energy flux in graphene in addition to the energy flux in the incident, totally reflected, coupled incident-totally reflected and evanescent wave packets.
