Methodologies for Electromagnetic Field Analysis Using Visualized Field Images

摘要

Image-based approaches for electromagnetic field analysis are introduced. Monochrome and color digital images visualize the scalar and vector potential distributions in the electromagnetic field, respectively. Two types of image equations express the visualized fields: Poisson and Helmholtz types of equations are considered as the governing equations of static and dynamic fields, respectively. The present article gives applications of the approaches in analyzing magnetic fields imaged by the sensor coils and scanning electron microscope. Finally, a methodology for image recognition demonstrates how magnetic field source elements can be identified.
