Extraction of equivalent dipole-moment model based on improve mapped matrix

It's a common inverse problem to research the near-field coupling and far-field radiation from a PCB circuit through using near-field scanning technique which reconstruct a Dipole-Moment Model based on the near-field plane data. Because of the noise consists in the data, it's a useful method to get a model which is not sensitive to interference by the regularization technique. As different condition numbers of the mapped Matrices, the dipole-moment model has diverse deflection. It's important for getting a stable and accurate dipole-moment model by selecting the best condition number.
