Adjoint Methods for Uncertainty Quantification in Applied Computational Electromagnetics: FEM Scattering Examples.

We present methods for quantifying uncertainty and discretization error of numerical electromagnetics solvers based on adjoint operators and duality. We briefly introduce the concept of the adjoint operator and describe applications of adjoint solutions for predicting and analyzing numerical error and approximating sensitivity of a given quantity of interest to a given parameter. Forward solutions are based on the higher order finite element method (FEM). [ABSTRACT FROM AUTHOR]
