Method for determining the electric and magnetic polarizability of arbitrarily shaped conducting bodies

The paper deals with polarization properties of arbitrarily shaped conducting bodies in quasistatic electric fields and quasisteady magnetic fields within the strong-skin-effect approximation. Based on measuring the capacitance (inductance) of a field-forming system before and after introducing an arbitrary conducting body into it, a method for determining its electric (magnetic) polarizability is proposed. The method permits one to find eigenvalues and directions of the principal axes of the polarizability tensors of any conducting body. The results obtained are useful in solving two practical problems of the electromagnetic compatibility: estimation of a measurement error induced by coupling the transducers of an electric and magnetic field to the conducting surfaces, and estimation of an additional field induced by coupling the objects to the field-forming system electrodes in electromagnetic susceptibility tests.
