Abstract: A novel time-domain adjoint sensitivity analysis (ASA) approach is proposed. Our finite-difference time-domain (FDTD)-based approach accelerates wideband sensitivity calculations for high-frequency structures with nonlinear media. The introduced approach supports simulated problems with current sources or… read more here.

DOI: 10.1109/tap.2020.3019576
Abstract: The difference scattering field has been defined for studying the scattering from a target above a randomly rough surface, which is independent of the selection of rough surface’s length theoretically. It is feasible to extend… read more here.
