Abstract :
This paper contains references to several problems in electromagnetic wave theory which have been solved by numerical methods. In particular, it treats the methods and machines employed by groups at the University of Michigan, Willow Run Research Center, and at the U. S. Naval Proving Ground, Dahlgren, Virginia, in obtaining on a high-speed computing machine a numerical solution for the radar cross section of a prolate spheroid. At the University of Michigan the work was under the direction of K. M. Siegel, while R. A. Niemann was responsible for that done at the Naval Proving Ground.
