A proposed measurement of the reverse Cherenkov radiation effect in a metamaterial-loaded circular waveguide

We have recently proposed an experiment on verification of the reverse Cherenkov radiation (RCR) effect in a left-handed-material-loaded waveguide. Applications of the RCR effect may range from novel higher-order-mode suppressors in microwave and millimeter-wave sources to improved particle detectors for satellite non-proliferation missions. The experimental configuration includes a circular waveguide filled with an artificial metamaterial with simultaneously negative permittivity and permeability, in which the electromagnetic wave with a frequency of 95 GHz will interact with an electron beam. We have demonstrated that for certain values of effective permittivity and permeability only the backward-propagating mode can be exited by the electron beam. At the conference we will present some newly developed metamaterial designs, which we plan to employ for producing the proper effective medium parameters for this experiment.
