	%X Change in impedance of an encircling coil is obtained
in the present paper for the case where the electric conductivity and
magnetic permeability of a metal cylindrical tube depend on the
radial coordinate. The system of equations for the vector potential is
solved by means of the Fourier cosine transform. The solution is
expressed in terms of improper integral containing modified Bessel
functions of complex order.
