The earlier attempts for numerical field solutions
employing the CSM were reported by Loeb and his colleagues
[1,2] and Abou Seada and Nasser [3,4]. In these
reports, field solutions were obtained for rod-plane [l-31
and cylindrical conductor-plane configurations [4]. Subsequently,
in a comprehensive paper, Singer, Steinbigler
and Weiss [5] presented the details of the CSM and its
applications to two- and three-dimensional fields having
rotational symmetry. Since then, many refinements to
the original method have been proposed and the CSM
has been successfully used to solve a variety of field
computation problems. Consequently, this method has
evolved into a very powerful and efficient tool for computing
the electric fields of HV devices.
