Andrejs Koliškins

Semi-analytical solution of an eddy current problem with azimuthal symmetry is considered in the paper. The change in impedance of an excitation coil is computed in the case where the coil is located above a conducting half-space with a surface flaw in the form of a cylindrical hole. The problem is solved using the TREE method. Results of numerical calculations are presented.
