INFERRED TWO-DIMENSIONAL SPATIAL CURRENT DENSITY DISTRIBUTION FROM MAGNETIC SOURCES
Abstract
The use of imaging has usually be an essential aspect of scientific investigations and medical diagnoses. In the applications of imaging for the above stated investigations and diagnoses, achieving optimal resolution of the reconstructed images is of prime importance. In this study, the magnetic inverse problem was solved via Fourier transforms to reconstruct two-dimensional current mappings. The dimensions of the conducting sheet, upon which the current density is to be reconstructed, as well as the distance of the magnetic source to the conducting sheet were varied, and the corresponding images of the current density were reconstructed. The thickness of a conducting sheet determines the spatial current density distributions and image resolutions. The spatial resolutions of the reconstructed current density images were higher at nanometer and micrometer scale magnetic source distance to the conducting sheet, and blurred at a millimeter scale distance.
