The dispersion relation for the interaction between the electron beam and the symmetrical mode propagating in this slow wave circuit is obtained, by means of the Variational method. The method to calculate the arbitrary order Bessel function with complex argument is discussed. The three dimensional trajectory graph of the Bessel function with complex argument is plotted. The instantaneous operating bandwidth can be estimated in terms of the relation between of the gain and frequency.
