It is, of course, assumed that the reader possesses a general knowledge of the electromagnetic field as normally gained Preface ix in a pertinent undergraduate course and that he is familiar with the principles of vector notation student and the teacher in advanced courses as well as to the professional engineer and the physicist in the research and development laboratory. Now, it has become clear that the scope of electromagnetic theory and its applications to problems of. necessary to recognize, and conveniently refer to, the proofs of existence and of uniqueness of solutions which have been developed by pure mathematicians. The burden of this great debt to the mathema- ticians has been lightened only because of the tremendous
