DEVICE/METHOD FOR CALCULATING RESISTANCE TO RADIATED ELECTROMAGNETIC FIELD AND PROGRAM RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To simulate a current flowing in an electronic equipment by means of radiated radio waves of an antenna at high speed by calculating a current flowing in the electronic equipment by due to radiated radio waves of the antenna by solving the simultaneous equations of the moment method having mutual impedance. SOLUTION: Structure information on the electronic unit of a simulation object is read from an electronic unit structure data file 2 and the electronic equipment and an antenna used for simulation are divided into elements. A first calculation means 10 sets a representative frequency on the carrier frequency/upper side band frequency/lower side band frequency of the radio waves which the antenna radiates and calculates the mutual impedance of elements in the representative frequency. A second calculation means 12 solves the simultaneous equations of the moment method having mutual impedance which the first calculation means 10 calculates and therefore current flowing in the electronic equipment is calculated by the radiated radio wave of the antenna with carrier frequency/upper side band frequency/lower side band frequency as calculation objects.
