Abstract: An independent current source and a voltage-dependent source are arranged at each of ports, and a voltage at each of the ports is calculated with a circuit analysis. A voltage source is arranged at each of the ports by using the calculated voltage value, and a current flowing in an analysis target is calculated with an electromagnetic wave analysis. An analysis time is incremented stepwise, and the calculation of the voltage at each of the ports and the calculation of the current flowing in the analysis target are repeated. As a result, an electromagnetic field intensity calculation can be made with high accuracy even for an analysis target where a plurality of ports exists between a circuit analysis model and an electromagnetic wave analysis model.

Abstract: A mesh processor divides a target device into a plurality of patches. A mutual impedance calculator computes a mutual impedance between the patches based on previously computed analytic solutions of a quadruple integration under the condition that the patches are rectangular in shape and are parallel or perpendicular to each other. Finally, an electromagnetic field intensity calculator calculates electromagnetic field intensity based on the computed mutual impedance.
