ABSTRACT
The method of magnetic tomography deals with low-frequency magnetic fields and is based on its high penetration of electrically conductive media. Therefore, this method is usually used for diagnostics of electrically conductive objects or for detecting fully conductive objects located behind dielectric obstructions. Moreover, weakly varying magnetic fields pass through metallic obstructions, allowing definition of the objects behind them. The components of magnetic fields have a narrow spatial spectrum far from the source and, therefore, have poor localization of the magnetic field at large ranges from the source, leading to a low resolution of the recovered tomographic images. It is seen that the magnetic field created by such current frames has a distributed character, but the weight center of this distribution is co-planed with that of the frame system. This result was proved by experimental data.
