Abstract :
An easily fabricated type of corrugated waveguide is described and a variational method is applied for the calculation of its propagation properties. The stationary functional is of unusual type, because the boundary susceptance of the corrugated guide is conceived as a nonstandard eigenvalue of the problem. The resulting method is tested with an ordinary corrugated guide.
