中文摘要	The impedance characteristics of a steel plane ground were analyzed to model the electromagnetic compatibility and the common-model electromagnetic interference between the electronics and the electric system on ships. The mechanism of the proximity effect on the steel impedance was analyzed with circuit theory relating the steel plane impedance and the exterior circuit in an equivalent circuit model with three impedances. The mutual resistances between the two common ground circuits were measured using the four terminal connected methods. For strong proximity effects, the analyses indicate that magnetic field coupling not only produces a mutual inductance but also an equivalent mutual resistance. The experiment measurements show that the steel resistance is 17 times larger at 1 MHz. The coupling resistance of the steel plane was calculated using FEM, with relative errors between the calculation and the measurements of about 17%.
