Investigation of Defects as a Loading Impedance of Waveguide

Abstract

The paper deals with non-destructive microwave measurement of metal defects exploiting the waveguide features at the defect shape evaluation, (e.g. quarter – waveguide transformer). As we notify in the foregoing article [1] we have paid our attention to the non-destructive investigation of metal cracks in microwave region. In this article some results concerning their evaluations regarding to microwave access are shown. From the series of measurements we present that one giving information about possible behavior of a crack.
