Analytical solution for the change in impedance of a coil located inside a two-layer cylindrical tube is obtained in the present paper. The electric conductivity and magnetic permeability of the inner layer of the tube depend on the radial coordinate. The properties of the outer layer are assumed to be constant. The solution is expressed in terms of improper integrals containing modified Bessel’s functions of complex index. Extension of the proposed model for multilayer tubes is discussed.
