A selective survey of computational electromagnetics

Some of the tools used in computational electromagnetics are placed into perspective with respect to the different kinds of approaches that may be used and their computer-resource requirements. Particular attention is paid to numerical models based on integral and differential equations. After a brief background discussion, some of the analytical and numerical issues involved in developing a computer model are reviewed. Some practical considerations are included from the viewpoint of computer-resource requirements, followed by a discussion of some ways by which computer time might be reduced. The presentation concludes with a brief examination of validation and error checking. The emphasis throughout is on review and summarization rather than detailed exposition
