Visualization of the current distribution on the body induced by low frequency emission by the inverse problem

Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we present a measurement technique to estimate current distribution on the body with a complex shape induced by electromagnetic resonant coils of wireless power transmission. To estimate the current distribution, we have used an inverse propagating problem. In general, inverse propagating problem is ill-posed. Therefore, we have used the Tikhonov regularization. Also, we determine the regularization coefficients by L-curve method. Since the number of measured data should be larger than the unknown current elements, we reduce number of the mesh of vehicular CAD data by deformation structure. We demonstrate that an area flowing strong current can be estimated using near field measurement data.
