ANALYSIS SYSTEM OF ELECTROMAGNETIC FIELD WAVE SOURCE

PURPOSE:To enable current distribution to be calculated from an electromagnetic field measured by an electromagnetic field measuring device and at the same time to control an electromagnetic environment by utilizing information of the electromagnetic field predicted by the current distribution designed artificially. CONSTITUTION:An electromagnetic field close to a wave source of an electromagnetic field measurement device 10 is measured. obtaining an electromagnetic field data, where a measurement value is first read and then a constant which is used by an electromagnetic equation is input. Furthermore. a green function is calculated, obtaining current distribution by the method of least squares. The data is compared with a desired electromagnetic field and a user can improve wave source distribution if there is a need for improvement. On the other hand. an artificial current distribution is designed by a user, a new current distribution is proposed, and the electromagnetic field in that case is calculated by an electromagnetic field prediction program, where a user who treats a physical wave source distribution performs treatment for improvement based on current distribution before treatment, a proposed current distribution, and the electromagnetic field according to the proposed current distribution. The result can be confirmed by the measuring device 10.
