Wideband Second-Order Adjoint Sensitivity Analysis Exploiting TLM
Abstract
We present, for the first time, an efficient adjoint variable method (AVM) for estimating second-order sensitivities exploiting time-domain transmission-line modeling. For a structure with ${\mbi n}$ designable parameters, the complete Hessian matrix of any desired objective function is estimated using ${\mbi n}$ extra simulations as compared to $O({\mbi n}^2)$ using the traditional finite-difference approaches. Our approach is illustrated …
