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.
