Radiation From an Open-Ended Waveguide With Extended Dielectric Loading


  • T. T. Fong


The relative contributions of leaky, surface, and space waves are studied for an open-ended dielectric-loaded waveguide structure using Wiener-Hopf technique with the key step in factorizing the kernel being carried out numerically. The relative field contributions are evaluated by both ordinary saddle-point and modified saddle-point integration methods, and the accuracy of each method in different spatial regions is examined.
