Abstract
The process of electromagnetic field modeling with the MMP (multiple multipole) code is described. A short overview is given of the generalized multipole technique (GMT) on which MMP is based. The advantage of the field concept versus circuit models is discussed, and the important features of the MMP code are summarized. The appropriate choice of the expansion functions is treated. Simple geometrical rules are sufficient for finding a well-converging expansion. Boundary condition weighting is considered. Knowledge about the order of magnitude of the expected solution makes the treatment of complex situations with high dynamics considerably easier. An explanation is given of how to make use of symmetry or partial symmetry to greatly reduce computation time and computer memory requirements. A general method for treating complex systems using a step-by-step solution technique, is described. Two electromagnetic-compatibility (EMC)-oriented examples are given: the problem of coupling through apertures and the more complicated problem of the Hubing benchmark, which has not yet been solved completely. >
