Abstract
The main inverse electromagnetic problems are formulated and solved for testing and inspecting of many devices such as thin-film transformers, inductors, printed circuit boards, motherboards of personal computers, etc. The visualization technique is applied to determine the current distributions and for nondestructive detection of the magnetic materials by locally measured magnetic fields. The image of the field distribution is processed using field theory. The color-source densities have been evaluated from the color distributions of the field data set. It was found that the color-source distribution corresponds to the field source distribution. Generating new color distribution with obtained color-source densities can essentially reduce the noise of the measured field data. With the proposed approach the quality of the images can be essentially improved. The results obtained show that various inverse electromagnetic problems can be successfully solved using visualized information of field distribution and image processing techniques.
