摘要
This work is dedicated to the calculation of the electromagnetic field created by an arbitrary current source in the proximity of a cylinder consisting of a certain number of concentric layers made of materials with various electrical conductivities and magnetic permeabilities, using the method of the transfer matrix. The general results obtained are then particularized for the case of an eddy current transducer with a rotating magnetic field, having its reception part of a special construction. The inversion method used to determine the thickness of the protective coatings on a conductive cylinder is presented.
