Abstract:
A radiating electromagnetic wave analysis apparatus which analyzes an electromagnetic wave radiating from a multilayer substrate, comprising:signal layer electric current distribution computation means for obtaining distribution of an electric current flowing through a signal layer using a distributed constant line approximation method or a transmission line analysis method, and for generating a model of the multilayer substrate where electric currents, which are obtained by dividing an electric current of a wave source in the signal layer, are respectively inserted between a power supply layer and the signal layer, and between a ground layer and the signal layer as electric sources;multilayer substrate electric current distribution computation means for computing distribution of an electric current of an entire multilayer substrate, including the power supply layer and the ground layer, in a moment method based on the distribution of the electric current in the signal layer, and the model where the electric current sources are respectively inserted between the power supply layer and the signal layer and between the ground layer and the signal layer: andradiating electromagnetic field intensity computation means for computing electromagnetic field intensity of an electromagnetic wave radiating from the multilayer substrate based on the distribution of the electric current of the entire multilayer substrate.
