Abstract :
The accuracy of numerical electromagnetic analysis is limited by numerous sources of error. Dynamic range is a fundamental limitation due to the finite precision arithmetic used by computers. This limitation, as well as limitations involving box resonances and subsectioning approaches, is explored quantitatively. In this way, users of such software can gain an understanding as to the range of problems for which a numerical electromagnetic analysis can give accurate answers, and the range for which the results may be in question.
