The Extraction of Engineering Information from a Potential Solution to an Electromagnetic Field Problem

Abstract

In recent years it has become necessary, for both technical and economic reasons, to obtain accurate solutions for the electromagnetic field in complex devices. The complexity may be introduced by the geometric shape, the material properties, time dependence or a combination of all of these. Traditionally, these devices have been designed using a mixture of simplified, algebraic, closed form solutions, experimental evidence and design experience. However, the cost of prototypes may be prohibitively high, there may be little or no experience available, and algebraic methods, whilst convenient to use, are unable to model many of the complexities.
