Abstract
A simulation apparatus for simulating the current flowing through elements of an electronic apparatus using the moment method based on reaction matching and able to achieve high speed simulation processing, comprising a segmenting means for segmenting the electronic apparatus to be analyzed into elements, a calculating means for calculating a mutual impedance between segmented elements of the electronic apparatus, assuming that a triangle function current flows through the monopoles, by using an approximation equation of the mutual impedance between monopoles, expressed by a polynomial of the power of k, derived by exp(-jkr) which is approximated by multiplication 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), and a simulating means, by using the calculated mutual impedances between elements, for finding the current flowing through the elements of the electronic apparatus in accordance with the moment method.
