  • Abstract
    Summary form only given. In this work, a coaxial virtual cathode oscillator (vircator) has been investigated. Horn antennas are widely used in the output of high power microwave tubes. The output characteristics of a vircator circular horn antenna with TM mode operations are studied. A 3D model has been constructed using the finite-element code, HFSS, and the numerical results have been carried out after time consuming simulations. The calculated far-field patterns of TE11 and TM01 modes for the vircator output are presented.
