Role of Classical Time Domain CEM Methods for Quantum Electromagnetics

As quantum theory matures, quantum applications that significantly depend on electromagnetic effects are becoming increasingly of interest to engineers. We discuss a number of diverse computations that are needed in the engineering design of various devices leveraging these quantum effects. In each case, the broadband knowledge of the classical dyadic Green's function of the problem being analyzed plays an important role. As a result, many of these applications require the extremely broadband solution of classical electromagnetic scattering problems in complex geometries to evaluate components of the dyadic Green's functions. This suggests that classical time domain computational electromagnetics methods will play an important role in the future of quantum applications.
