Abstract :
A method of measuring the coupling impedance in slow-wave structures (SWS) is presented and analyzed in this paper. This method is based on comparisons of the resonant frequencies of a SWS with and without the longitudinally conducting probe. Using these frequencies, we derive an expression for the wave impedance of a sheet electron beam in a planar SWS with a rectangular cross section.
