FDTD-Based Adjoint Sensitivity Analysis of High-Frequency Nonlinear Structures
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 incident field excitation. Using only one extra system simulation, the sensitivities of a general objective function/response are estimated …
