Nondestructive inspection and characterization of complex engineering materials via ultrasound techniques.
… were inspected with this technique, and the wave scatter was observed using a c-scan technique. The wave scatter varied considerably from the isotropic aluminum plate to the laminated composite plate, and the wave scatter is shown to be a function of the number of lamina within the part. …

Digital holographic imaging of aquatic species
… produced by the interference between a reference wave and the wave scatter by a coherently illuminated object with a charge-couple-device (CCD). The recorded hologram contains information about the amplitude and phase of the optical field as modified by the object. This optical field is retrieved …

Damping of Vibration Using Periodically Voided Viscoelastic Metamaterials
… previously to improve the damping of vibrational waves and acoustic waves through wave scattering and wave reflection at periodic impedance changes. Impedance changes can occur at both material boundaries and geometric changes of the medium. Impedance changes cause wave scattering, wave …
