Abstract :
The authors explore various possible approaches for generating lowest order and higher order bases for modeling surface currents and their divergence for moment method application to integral equations. The bases developed are defined on curved triangular and quadrilateral elements. All the bases are conveniently defined in parent element coordinates, and each expansion function spans one or two patches.
