A brief history of early computational electromagnetics at the Ohio state university ElectroScience Laboratory

This paper will survey the history of computational electromagnetics (CEM) at The Ohio State University Electroscience Laboratory (ESL) prior to 1990. By computational electromagnetics, it is meant a numerical technique in which the unknown currents or fields are expanded in terms of N basis functions, and the unknown coefficients in the expansion are found as the solution of a matrix equation Prior to 1990, virtually all of the CEM work at the ESL was with the Method of Moments (MM), and thus this article will focus solely on the MM.
