MW NDT An Inspection Method
The purpose of this paper is to provide a broad and introductory perspective to MW and provide the technical justification as to why MW should be its own method in support of ASNT’s recognition of MW. There is not enough room in this paper to give justice to all of the formidable techniques, example applications, and noteworthy contributions since 1950s, when MW began. Moreover, there is insufficient room to even simply list the references. The goals of this paper are to introduce MW, describe materials characterization and imaging techniques with example applications, and a final discussion. Materials characterization describes transmission line, open-ended waveguide, and free-space techniques, image describes near field, lens-focused, synthetic-focused, and real-time techniques.
Keywords: microwave testing, material characterization, imaging.
