On the theory of irisloaded waveguides
Abstract
Propagation of electromagnetic waves in a class of periodic waveguides typified by the circular irisloaded 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 irisloaded waveguides. The phenomenon of relative convergence was observed and studied by means of the asymptotic behavior of the expansion coefficients.
