Abstract

The strong limitations on the applicability of exact methods of analysis to electromagnetic boundary-value problems have encouraged the development of certain approximation techniques. Among the most practical of these techniques is Schwinger's variational method. In this paper Schwinger's variational principle is derived from first principles and its application to antenna theory is critically examined. La limitation de l'application des méthodes exactes d'analyses aux problèmes électromagnétiques comportant des conditions aux limites a encouragé le développement de certaines méthodes d'approximation. La plus pratique de ces méthodes est la méthode variationelle de Schwinger. Dans cette communication le principe variationnel de Schwinger sera dérivé de principes fondamentaux et on examinera de facon critique son application à la théorie des antennes.
