摘要: The letter is concerned with the nature of evanescent modes in circumferentially corrugated cylindrical waveguide. When longitudinal surface susceptance small, propagation coefficients for these must become complex. A knowledge necessary when discussing discontinuities waveguides; some preliminary results a modal analysis step-discontinuity problem waveguide are presented.
