Abstract

In this paper we have studied the electromagnetic field scattering on ideal surface breaking and subsurface cracks, solving the forward and inverse problems of diffraction. The aim of this paper is to present the possibility of the evaluation of position and severity of long and thin cracks in electrically conductive materials. This procedure presents the advantage of reduced calculation time and power, reported for the classical inversion method. The simulated data are compared with experimental data, being in good correlation.
