Abstract

A general approach to experimental modeling of Cherenkov and diffraction radiation in vacuum electron devices employing periodic metal-dielectric structures is presented. The potential benefits and drawbacks of this approach to the design of microwave devices are discussed. The approach is based on resemblance of electromagnetic properties between the modulated electron beam and the surface wave in a dielectric waveguide. A dedicated millimeter-wave experimental setup is developed and constructed.
