Abstract
The problem of propagation of dominant TE mode, in the twisted wavegui de of rectangular cross-section is analysed up to 12th order perturbat ion terms. The helical coordinate system is used for the mathematical formulation of the problem and perturbation technique is used in obtai ning the solution, It is shown that for, accuracy of the results the c ontribution of higher order perturbation terms cannot be neglected. Th e information about the percentage contribution of higher order terms is worked out. This is useful in deciding the number of terms to be in cluded for the expected accuracy.
