Acoustic Emission
Acoustic emission (AE) and micro-seismic activity are naturally occurring phenomena. Almost all materials emit sound or acoustic emission when they are sufficiently stressed. Wood and rock produce AE signals in audible frequency ranges when stressed.

Elastic wave propagation in a bounded medium significantly differs from that in an unbounded medium. The bounded medium in the form of a cylinder acts like a solid waveguide directing the wave with its geometry. A continuous or a pulsed wave interact

In the earlier phases of the Microwave Tube Built-In Test (MTBIT) program (1999-2001), a new advanced nondestructive testing technique was demonstrated using acoustic emission (AE) for in-situ monitoring of normal and abnormal performance of high- po

Failure analysis of integrated circuit (IC) packages is a critical element for in house quality control and for problems encountered in service. Plastic IC packages are routinely inspected for delaminations, voids, cracks, and corrosion using the C-m
