On the theory of iris-loaded waveguides
Abstract
Propagation of electromagnetic waves in a class of periodic waveguides typified by the circular iris-loaded structure is investigated. A model field matching procedure on planes perpendicular to the direction of propagation is employed. The dispersion relation is determined by a generalized eigenvalue equation, which is reduced to a determinantal equation. Several mathematically equivalent formulations are presented, in particular, a solution which does not involve matrix inversions. Numerical results are obtained for the lower passbands of the accelerating and deflecting modes in iris-loaded waveguides. The phenomenon of relative convergence was observed and studied by means of the asymptotic behavior of the expansion coefficients.
