VARIATIONAL NATURE OF GALERKIN AND NON-GALERKIN MOMENT METHOD SOLUTIONS

The variational aspects of secondary calculations based on a method of moments (MoM) solution are investigated. These calculations exhibit a type of second-order accuracy, regardless of whether or not the opera tor being discretized is self-adjoint, and regardless of whether or no t testing functions are identical to the basis functions (Galerkin's m ethod). Numerical results support these conclusions and suggest that t he advantage of Galerkin's method in actual calculations is grossly ov erstated.
