Abstract(in English) In this report, we propose the equivalent lumped element circuits for the KEC electric and magnetic SE(Shielding Effectiveness) test fixtures. The magnetic SE test fixture's equivalent circuit was constructed by introducing the Z-matrix of coupled transmitting and receiving antennas which was calulated by 3D-FDTD model. As a result, the magnetic test fixture could be replaced by a transformer model which has third coil whose load impedance is the sheet resistivity of the shielding maetrial. The calculated SE by this model agrees well with the measured result within 3dB. The KEC electric SE test fixture wasmodeled by an equlvalent lumped element circuit. Through this modeling, another shielding material parameter was found to be necessary for the characterization of shielding material with small apertures.
