New directions in computational electromagnetics

Computational EM (CEM) is a very active field, as is evident from a quick glance at the literature, comprising of journal papers as well as proceedings of symposia in the areas of Antennas, Propagation, Microwave Circuits, and Metamaterials, just to name a few. A variety of CEM tools that are based on the Integral Equation techniques, e.g., the MoM and TDIE, and Finite Methods such as the FEM and FDTD, are available to us for solving a wide range of EM problems. The above CEM methods have recently been embellished by combining them with innovative techniques such as the FMM for MoM-based algorithms, Discontinuous Galerkin approach for FEM, and extensive Parallelization for the FDTD. This development has, in turn, enlarged the scope of the type and size of currently solvable problems that would have been totally unthinkable even just 10 years ago. So, we can rest assured that CEM is not a dead field after all, as some self-appointed pundits would have us believe.
