In the present paper we consider the solution of the eigenvalue problem for the following three cases: (1) a coil with alternating current above a conducting cylinder of finite size, (2) a coil above a conducting plate with bottom cylindrical hole and (3) a coil above a conducting half-space with a flaw in the form of a cylinder of finite size. Computational algorithm is described and results of numerical computations of eigenvalues are presented for all three cases mentioned above.

Keywords
complex eigenvalues, eddy current method, Cauchy theorem
