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.
