In this thesis a numerical technique is developed determining the propagation constant

in waveguides and transmission lines. The technique accounts for both dielectric and conductor

losses in a guide having an arbitrary cross section and uses a full-wave solution process. A set of

coupled, vector integral equations which characterize the system are derived. The equations

enforce the necessary boundary conditions on the tangential electric and magnetic fields at the

boundaries separating the conductors and dielectrics.

The method of moments (MOM) technique is used to cast the equations into a

numerically solvable form. Computed results for various waveguide structures are compared to

known or perturbed results for three well—known structures. However, the program is more

general and may be applied to other cross-sections. Finally, possible future extensions of the

work is presented.
