Abstract
Recently, faulty operation by mutual interference among electric and electronic devices has become a social problem, which is caused by widely spread personal computers and cellular phones. A solution to overcome this difficulty is to estimate the current distributions from locally measured magnetic fields.
In this paper, we propose two methods, one is the direct inverse method and the other is the generalized vector sampled pattern matching (GVSPM in short) method, for estimating the current distributions in a square cubic box. First, we solve inverse source problems in order to estimate the 2D current distributions from locally measured 2D magnetic fields. Second, we combine the estimated 2D current distributions to obtain quasi-3D current distributions. Preliminary experimental results indicate the validity of the proposed methods.
