Abstract
A numerical solution method for two-dimensional electromagnetic held : problems is presented using the B-spline finite-element expression bas ed on polar coordinates. The technique has two main advantages: (1) to avoid the truncation errors at some curved boundaries and (2) to impr ove the accuracy of singular boundary-value problems with a sharp corn er. The B-spline finite-element formulation in polar coordinates is de rived and its numerical applications are illustrated by an eddy curren t problem and several waveguide eigenvalue problems.
