Some Problems and Improvements in Applying Point-Matching Method to Moment Method Analysis

In the moment method analysis, the point-matching technique, due to its simplicity, explicit physical interpretation and moderate computing time, has found wide applications in EM problems. But it has the demerits of unstability and poor convergence of the solution.In this paper, the influences of the choice of matching point positions on the solution for thin wire antennas are investigated from the two-potential equation. A procedure for improving the computational accuracy and the convergence property is introduced. A technique for saving computing time is given.
