Network analysis of leakage characteristics for dielectric ridge guides with non-rectangular profiles

Leakage characteristics of dielectric ridge guides with non-rectangular cross section are analyzed by a method that combines the mode matching procedure with the staircase approximation and multimode microwave network theory. Our emphasis in this paper is on the parametric effects of cross section profile on leakage properties of the ridge guide. Some numeral results with their explanations are given for practical reference.
