Computational Electromagnetics Research Group Front Page Professor Hakan Bagci leads the so-called CEM research group, which stands for Computational Electromagnetics Research Group Computational electromagnetics (CEM) is the science of designing and implementing fast and accurate Maxwell's equations solvers. The field of computational electromagnetics complements many branches of applied electromagnetics that often rely on experimentation. As importantly, it is an interdisciplinary field that interacts profoundly with the applied mathematics and computational sciences.
