Apparatus and method for calculating the strength of an electromagnetic field radiated from an electric device

A method of calculating the strength of an electromagnetic field radiated from an electric device according to a moment method, wherein the moment method is based on integral equations derived from electromagnetic equations, comprising

• interactively setting a name of a two wire cable arranged in the electric device and coordinates of the two-wire cable at a cable inlet, a cable outlet, and way points in the electric device, the way points being prepared as and when required to bend the cable between the two-wire cable inlet and the cable outlet;
• storing, in library means corresponding to cable names, respectively, the attributes of a corresponding cable comprising of the name, type, characteristic impedance, and structural data of the two-wire cable;
• generating a moment-method model of the two-wire cable according to the attributes of the two-wire cable read out of the library means corresponding to the set name of the two-wire cable and the set coordinates of the two-wire cable at the cable inlet, cable outlet, and way points;
• and
• calculating the strength of the electromagnetic field radiated from the electric device according to the moment-method model of the two-wire cable and the moment method.
