Surface Charge Simulation Method (SSM)

The surface charge simulation method (SSM) is similar to the charge simulation method (CSM). In these methods, the real source distribution is simulated by a great number of accumulated or surface charges. They are both convenient for solving open boundary and 3-D problems. SSM can solve field problems that cannot be solved by CSM and also those that can. Using SSM one can obtain solutions to problems containing a number of dielectric materials and problems having thin electrodes. Hence SSM is a more general method than CSM. One could also consider it to be a kind of boundary element method, or a method of equivalent source.
