| Abstract(in English) | To suppress the electromagnetic wave which is leaked from electrical circuits and devices, it is necessary to know the location of current sources. The improved sampled pattern matching (SPM) method was proposed to estimate location of current sources by using near-field distribution. Improved SPM method can estimate the location of current sources with phase difference, but it is invalid to estimate the magnitude of current sources. In this paper, we propose a method for estimating magnitude of current sources by using both improved SPM method and solving the matrix equation with direct inversion method which uses the location of current sources obtained from improved SPM method. The method is verified and compared with the experiment results. |
