Method, device and computer program product for determining an electromagnetic near field of a field excitation source for an electrical system

摘要

The method involves defining electrical and magnetic properties of material distribution of a system in each of partitions within a domain under consideration. A field excitation source (28) is defined within the system. Electromagnetic near-field components (40) within the partitions by solution of Maxwell's equations of a near-field are determined by considering defined material distribution. Each near-field component of partition is represented by a linear position of predetermined ansatz functions orthogonal to one another with regard to a scalar product and weighted with coefficients. Independent claims are also included for the following: (1) a device for determining an electromagnetic near-field of a field excitation source of an electrical system, comprising a partitioning unit (2) a computer program product comprising a set of instructions for determining an electromagnetic near-field of a field excitation source of an electrical system.
