Local error estimators are investigated for use with numerical solutions of the electric field integral equation. Three-dimensional test targets include a sphere, disk, NASA almond, and a Lockheed Martin Expedite aircraft model. Visual plots and correlation coefficients are used to assess the accuracy of the estimators. It is shown that the inexpensive discontinuity estimators are usually as accurate as the residual method.

The present paper aims to compare Harrington's direct method of moment (MoM) with the conjugate gradient method (CGM) by evaluating the total current solving the electric field integral equation (EFIE). Based on their performances, the number of iterations needed for convergence, storage, and the level of precision, it is found that the direct MoM is more efficient than other iterative CGM.
