Description

The objectives of this work were to develop an electromagnetic scattering model that can be used to predict the microwave scattering from a crack in a metallic surface, and to evaluate the potential of using microwave scattering measurements to determine the dimensions of the crack. The initial approach to this problem has been to model the surface crack as a section of rectangular waveguide shorted at one end. Theoretical and experimental results are presented for this case, and the potential for obtaining a quantitative evaluation of the crack dimensions is discussed.
