Excerpt from Basic Mathematical Investigations in Electromagnetic Wave Theory: Final Report, January 1, 1964 December 31, 1968 This report is a summary of research activities pursued during the period from January 2, 1964 to January 1, 1969 by the Division of Electromagnetic Research of the Courant Institute of Mathematical Sciences at New York University, under Contract Number AF 19(628)3868 with the Air Force Cambridge Research Laboratories. The research program was a continuation of work done under Contract Number AF 19(604)5238 with the same agency. The object of the research was to extend existing knowledge of classical electromagnetic theory with emphasis on electromagnetic wave-guiding radiation and communication, and diffraction problems. Investigations have been conducted in various areas in accordance with these objectives and are explained in the body of this report.
