Abstract:
1. A computer implemented method for optimizing an electromagnetic near-field of a field excitation source of an electrical system within a three-dimensional (3D) domain under consideration comprising a 3D computer model of the system split into N partitions, the partitions being described by a tetrahedral or mixed grid containing at least one tetrahedral cell, comprising: defining, using a computer, electrical and magnetic properties of the material distribution of the system in each partition within the domain under consideration; defining, using the computer, at least one field excitation source within the system; determining, using the computer, the electromagnetic near-field components within all partitions by solving Maxwell's equations of the near-field, taking into account the defined material distribution and the defined field excitation source, updating parameters of the system, based on the determination of the electromagnetic near-field components, with respect to an antenna radiation behaviour, a beam direction optimization, a suppression of cross-talk, an optimization of a transmission or reflexion of electromagnetic waves or a minimization of a stray field of said electrical system, whereby individual component parameters including at least one of material properties, mechanical dimensions and/or excitation frequencies of said electrical system are varied within the framework of the optimization process, where each near-field component of each partition is represented by a linear position of M predetermined ansatz functions P
