He has completed his PhD in applied mathematics department at the same university[3] under the supervision of Bernard Friedman in 1963; his dissertation involved the study of boundary value problems for Maxwell's equations.
[3] In 1966, Yee published a paper on the use of a finite difference staggered grids algorithm in the solution of Maxwell's equations.
Appearing on IEEE Transactions on Antennas and Propagation, the article received little attention at the time of its release.
[2] The incorrect numerical stability conditions on Yee's paper were corrected by Dong-Hoa Lam in 1969[7] and Allen Taflove and Morris E. Brodwin in 1975.
He became a consultant to Lawrence Livermore National Laboratory in 1966, working on microwave vulnerability problems at the same institute from 1984 to 1987.
