✦ Synopsis

The accuracy of the charge simulation method of calculating electrostatic fields can be improved by optimization techniques that involve the determination of the best location and strength of each individual charge and its image. This paper presents a method that eliminates the optimization of the location of the charges by considering the charges to be distributed in a certain manner on the surface of the object. It is basically an integral technique applied to the method of moments. A simple least-square procedure is employed to reduce the r.m.s, error in potential on the surface. Results are presented to illustrate the greater accuracy achieved and the advantages as well as disadvantages of this method.

The Trefftz method may be described in terms of an integral equation formulation based on eigenfunction expansions rather than the usual element (BEM) solution method. Using an 'Embedding Integral Equation' approach, the Trefftz method may not only be seen to be related to integral equation methods
