DOI: 10.1109/tap.2020.2969716
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.
