Abstract

We propose a novel kind of terahertz radiation source utilizing grapheme surface plasmon polaritons (GSPPs) excited by parallel moving electron beam. Theoretical analyses show that terahertz radiation can generate from graphene sheet on a periodic grating structure. The intensity of the radiation are greatly enhanced due to GSPPs and the frequency of the radiation can be widely tuned by both of the electron beam energy and chemical potential of graphene. The experiment based on this mechanism are in progress.
