... at the spall plane causes the tensile stress to decrease rapidly to zero. As a result, a compression wave forms in the matter adjacent to the spall plane region. These waves propagate in each direction away from the spall plane. At the rear surface of the target, as in Fig. 4 where the particle velocity...

Ultrasonic waves in the megahertz region are severely attenuated in air and cannot propagate in a vacuum. An ultrasonic beam is similar to a light beam. Both obey general wave equations and each travels...
