Abstract
In order to enhance the radiation energy of reversed Cherenkov radiation (RCR), on the basis of the single charged particle model, we developed a theoretical method using a charged particle beam bunch to enhance RCR in a circular waveguide partially filled with anisotropic double-negative metamaterials (DNMs). In this case, the reversed radiation mechanism is further illustrated. Numerical example shows that the radiated energy can be effectively enhanced by increasing the charged particle number in a short bunch and thus be readily detectable. The method reported here offers a theoretical basis for directly observing RCR using a charged particle beam bunch.
