Paper Abstract

Microwave and millimeter wave nondestructive methods using open-ended sensors have shown great potential for detecting minute thickness variations in laminate structures, in particular those backed by a conducting plate. Similarly, slight variations in the composition of dielectric materials may also be detected using a set of optimal parameters which include the standoff distance and the frequency of operation. In this paper the potential of using an open- ended rectangular waveguide for detecting the presence of rust under common paint and composite laminate coatings will be demonstrated. An experimental scanned image of a steel specimen with an area of induced corrosion will also be shown.
