Abstract

Accurate integration of singular and near-singular functions is critical to the accuracy of the method of moments solution to integral equations. While this problem has been widely addressed for flat geometries, their extensions to higher order surface descriptions have been limited. This paper provides a comprehensive prescription for the application of the singularity cancellation schemes to higher order surfaces. We present implementation details and demonstrative results.
