Plasmons in graphene traversed by relativistic electronic beam with arbitrary trajectories

Synopsis In this work we study the energy loss of a beam of relativistic electrons impinging on a graphene sheet under oblique incidence. Using several models for the electric conductivity of graphene, we cover a wide range of frequencies of the energy loss spectrum, from the terahertz to the ultrav...

Description
Summary:Synopsis In this work we study the energy loss of a beam of relativistic electrons impinging on a graphene sheet under oblique incidence. Using several models for the electric conductivity of graphene, we cover a wide range of frequencies of the energy loss spectrum, from the terahertz to the ultraviolet. To describe this spectrum, we consider the contribution of electronic excitations as well as that of transition radiation.
