摘要： A method for calculating the intensity of an electromagnetic field emitted from a device and a storage medium for storing a program of the method are disclosed. The method uses a moment method in which a mutual impedance between shell elements and a supplied voltage are assumed to be known quantities and the current flowing through the shell element is assumed to be an unknown quantity. The method comprises the steps of obtaining a plurality of shell elements including at least one triangular shell element by virtually dividing the device into a mesh, and setting an unknown quantity of a current directed from each side of the triangular shell element toward its apex only when a conductive wire is connected to the apex, setting an unknown quantity of a current directed from each side of the triangular element toward its apex when the side is common with a side of the other shell element, or setting an unknown quantity of a current parallel to a side of the triangular shell element when there is a shell element adjacent to the triangular shell element.
