Electromagnetic Field Source Searching from the Local Field Measurement

First, we make a brief review of inverse problems in various fields and formulate the inverse problems in the electrostatic, magnetostatic and current flowing fields. Secondly, we propose one of the methods for obtaining a unique solution pattern, not a unique solution of the inverse problem. Finally, we apply our method to human heart diagnosis and current flow estimation in a human brain. As a result, the positions of defects in hearts exhibiting the Wolff-Parkinson-White syndrome are successfully identified and sequential current flows in a human brain are clarified by our approach.
