Abstract
This paper extends the unstructured support operator method (SOM) into waveguide problems. The discrete operators derived in SOM satisfy the identities and theorems of scalar and vector calculus in discrete form. The algorithm derived here contains no spurious modes because the divergence-free condition guarantees no spurious charge. The paper presents good results for typical waveguide problems on the nonorthogonal, nonsmooth, and unstructured grids. The Arnoldi method solves the generalized eigenvalue problem with great efficiency.
