Abstract

A new mode convertor, which has four coaxial cable connectors and four semi-rigid cables situated circumferentially, was fabricated to propagate TE mode microwaves in a circular pipe in order to detect axial cracks appearing in the inner surface of the pipe. In this study, the reflections were measured using a network analyzer by propagating microwaves as a pulse through the mode convertor into a brass pipe that contains the slit on the inner surface. The reflections were evaluated with different orientations, lengths, and positions of the slit. The experimental results showed a clear difference between the signals with and without the slit.
