Computational methods in transient electromagnetics. A selective survey

摘要

We can now solve real-life problems in electromagnetics at all levels of complexity. Several popular algorithms are available to deal with the transient-scattering problem. They all solve either differential or integral equations in one form or another. No one method is best in all situations. Since only differential or integral equations are involved in the final solution, the methods described in this paper should be of considerable interest to other areas of science as well. Each of the methods available for predicting transient behaviors and responses has certain advantages and disadvantages, so an approach must be chosen carefully, depending on the problem complexity.
