Abstract
In order to localize unknown low frequency coherent current sources, we use an inverse problem with Tikhonov regularization. In order to perform a more accurate localization for a limited measurement data, we have used the L-curve to the regularization. The validity of the proposed method has been confirmed by experiments. We can estimate the locations of low frequency (850 kHz) coherent sources on the metal plate within the accuracy of 10cm.
