Abstract:
A simulation apparatus for simulating current flowing through elements of an electronic apparatus using a moment method based on reaction matching, comprising:segmenting means for segmenting the electronic apparatus to be analyzed into elements in accordance with configuration information of the electronic apparatus;calculating means for calculating a mutual impedance between elements, segmented by the segmenting means, of the electronic apparatus, assuming that a triangle function current flows through monopoles, by using an approximation equation of a mutual impedance between monopoles, equation of the mutual impedance between monopoles, expressed by a polynomial of the power of k, derived by exp(-jkr) which is approximated by mutliplication of exp(-jkr.sub.0) and a Taylor expansion of exp[-jk(r-r.sub.0)] (where j is an imaginary number, k is a wave number, r is the distance between monopoles, and r.sub.0 is a representative distance between monopoles); andsimulating means, using the mutual impedances between elements calculated by the calculating means, for finding the current flowing through the elements, segmented by the segmenting means, of the electronic apparatus in accordance with the moment method.
