An error estimator is proposed for the moment method in 3D electromagnetic scattering analysis. The error in the surface currents is estimated by the difference between a given solution and an approximate higher-order solution on the same mesh. The approximate higher-order solution is obtained by solving local higher-order problems relating to each surface element, by using hierarchical basis functions. The efficiency and accuracy of the error estimator are evaluated by considering some test problems. The application of the error estimator within a simple In-adaptive analysis scheme is also demonstrated, which shows that it can be used to improve the convergence of the moment method.
