Computer aided simulation method for determining the electromagnetic field of an object

摘要

The simulation method involves determining an electromagnetic field of an object which includes several sections and several charges and currents. A global multi-pole development which presents the effect of the charges and currents of remote points, and a local multi-pole development which presents the effect of the loads and currents at points within each section are produced in form of a multi-pole development in each of the several sections. The electromagnetic field of the object is determined through a superimposition of the global multi-pole development and the local multi-pole development of the several sections.
