Description
Summary:We have proposed an experiment on verification of the Reverse Cherenkov Radiation effect in a Left-Handed-Material-loaded waveguide. Applications of reverse Cherenkov radiation effect may range from novel higher-order-mode absorbers in microwave and millimeter-wave sources to improved particle detectors for satellite non-proliferation missions. The experimental configuration employs 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. In this presentation we will discuss the results of simulations and different manufacturing and assembling techniques for the metamaterial-loaded waveguide.
