20110251832 | METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT FOR DETERMINING AN ELECTROMAGNETIC NEAR-FIELD OF A FIELD EXCITATION SOURCE OF AN ELECTRICAL SYSTEM - A method, a device and a computer program product for determining an electromagnetic near-field of a field excitation source of an electrical system are provided, in particular for analysis and/or optimization of an antenna radiation, of a cross-talk problem, of a signal reflexion/transmission, of a stray field, of an irradiation problem or the like. The method includes defining electrical and magnetic properties of the material distribution of the system, defining at least one field excitation source, and determining the electromagnetic near-field components within at least one and in particular all partitions by solution of the Maxwell's equations of the near-field, where each near-field component of each partition can be represented by a linear position of M predetermined ansatz functions P | 10-13-2011 |
