Abstract

The reflection coefficient of Fiberglass/Kevlar slabs, including a layer of a different material was calculated as a function of permittivities, thicknesses, defect depth, and microwave frequency. Experimental tests were done with a single-frequency, amplitude and phase sensitive circuit, and with a swept-frequency amplitude only sensitive set-up. In this latter case a suitable processing of data allowed effective and fast defect detection. First experiments on microwave heating for thermographic NDT were also performed.
