Air-coupled ultrasound has been used as a tool for surface profilometry and to inspect highly attenuative materials such as composite laminates and foams for voids or disbonded areas. Significant losses are experienced with air-coupled ultrasound a

It is well known that an ultrasonic beam provides a maximum echo reflection when the beam impinges at right angles to the surface. To this end, some inspection standards recommend using refracted angles that provide normal incidence to a weld bevel i
