Abstract
A new two-dimensional finite-element (FE) eigenmode solver has been de veloped, which is suitable for calculating cylindrically symmetric mod es. The quantity H-theta/r is used in the code to describe the electro magnetic fields instead of H-theta Or rH(theta), which is preferential ly used in the existing codes, and the new formulation with H-theta/r is found to show higher accuracy and smoother convergence with respect to the number of mesh points. Comparison is also made between linear and quadratic elements, resulting in remarkably higher accuracy by the latter.
