Abstract Chasing efficient methods to generate and manipulate Cherenkov radiation (CR) is always the lofty target of many scientific researchers. In this work, by combining optical topological transition (OTT) graphene hyperbolic metamaterials (GHMs), we study properties clarify mechanisms OTT CR for first time. Specifically, indicate two representative examples reveal potential in manipulating...

Abstract We theoretically study the transition radiation in framework of full Maxwell equations, when a swift electron crosses monolayer graphene. Based on Sommerfeld integration, we demonstrate frequency domain spatial distribution this free-electron radiation, which clearly shows broadband excitation both photons and graphene plasmons. Moreover, spectra for plasmons are analytically derived. ...
