The Transfer Impedance of Capacitive Electrodes and Insulated Wires on the Ground Surface

摘要

This article presents a formula for the capacitance of a thin disk over a conducting plane corrected for the edge effects and offers a number of generalized expressions for assessing the transfer impedance of capacitive electrodes over ground with finite conductivity. It is shown that the transfer impedance of an insulated wire on the ground in a wide frequency range is described by the Cole-Cole formula with an exponent parameter from 0.9 to 1.
