Figure 1. Schematic of the circular cylindrical monolayer graphene structure with dielectric loading.

Figure 1

Three-dimensional view (a) and side view (b) of the structure. The radius of the dielectric medium is ra, the radius of the trajectory projection of CEB in X-Y plane is r0, it moves at a velocity Inline graphic above the graphene layer with a cyclotron trajectory, Inline graphic is the cyclotron velocity of the beam around z axis, and vz is the z component of velocity.
