Processing of Measured Fields Using Advanced Inverse Method of Moments Algorithm

A higher-order inverse method of moments algorithm, employing smooth current and geometry representations, as well as a very noise-robust solution algorithm, was presented at last year’s ESA workshop. The fundamental properties of the algorithm, including quantitative results for the RMS error of the reconstructed surface currents, were illustrated using synthetic data with added noise. In this paper we investigate the properties of an iterative variant of the algorithm and show practical results from applying the higher-order algorithm to measured fields obtained in a spherical near field range. The presented examples are chosen to illustrate both antenna diagnostics and filtering applications.
