要約(英語): This paper investigates the modeling method of real earth in an experiment above a conductor plate. This paper advances the method of representation way of grounding electrode on real earth above conductor plate. This paper discusses the basis of representation way and availability of this way. The waveform is different between the case of a real earth and an Al plate after reflection comes back from the return end. The first reflected wave is affected by the impedance of a grounding electrode. This fact indicates that the grounding electrode should be carefully represented in an experiment above a conductor plate. To reduce the difference, the effect of the earth resistivity and the grounding electrode of a real earth is investigated. A simple RL model is proposed to represent a real earth, when an experiment is carried out above the conductor plate. The model circuit gives a reasonable accuracy in comparison with the real earth.
