APPLICATION OF CAUCHY INTEGRAL TO APPROXIMATE THE FIELD COMPONENTS AND CURRENT IN METAL DIELECTRICAL POLYGONS - Method of the Field (Current) Restoration Inside and Outside Flat Closed Contour based on Its Known Values at the Contour

摘要

The Cauchy integral was proposed as a means to approximate the field components and current in metal and dielectrical polygons. The report illustrates that such a technique can significantly scale down electromagnetic issues solved in spatial-frequency domain. The technique also makes it possible to evaluate the strength of electromagnetic field not only inside the considered closed contour, but outside it even in case when there is no a prior information about object configuration and its physical characteristics.
