Quasi-Two-Dimensional Current Visualization by Locally One Dimensional Method

Abstract

In this paper, we propose a visualization method of the quasi-two-dimensional (2D) current distribution by locally one dimension (1D) method.
At first, we measure a perpendicular magnetic field to a current distributing surface, and estimate current distribution by using the two-dimensional inverse analysis.
Second, we estimate the 1D X and Y current components from the 1D measured X and Y magnetic fields by using the 1D inverse analysis, respectively.
Finally, after convolving among the 2D and locally 1D current vectors, it is possible to evaluate the quasi-2D current distribution. As a result, it is found that more detailed current visualization than those of 2D inverse analysis is possible by convolution among the 1D and 2D current vectors.
