We present methods for quantification of numerical error for computational electromagnetic solvers using adjoint operators and duality. We outline the concept of adjoint operators and further introduce applications of the adjoint problem toward analyzing numerical error of forward solutions. We give an illustrative example of contribution to the total error on an element-wise basis for a 1-D slab scattering problem solved by a higher-order finite element method.
