This paper proposes a brief review of acoustic wave scattering models from rough surfaces.
This review is intended to provide an up-to-date survey of the analytical approximate or semi …

Rayleigh waves are well known to attenuate due to scattering when they propagate over a
rough surface. Theoretical investigations have derived analytical expressions linking the …

Fatigue damage is a common cause of failure in welded structures, and it is often difficult to
detect it in the early stage. While ultrasonic-based methods can effectively monitor crack …

Ultrasonic non-destructive evaluation techniques, such as time-of-flight diffraction (ToFD) for
which the arrival times of waves diffracted from crack tips are analysed to locate and size …

The value of using permanently installed monitoring systems for managing the life of an
engineering asset is determined by the confidence in its damage detection capabilities. A …

Elastic wave scattering from a randomly rough surface of a finite length includes surface
reflections and diffractions from the tips. Previous research has focused upon reflection …

Elastic waves scattered by randomly rough surfaces in solid media play an important role
across research topics including ultrasonic wave detection and imaging, seismic wave …

To investigate accurately unique and advanced wave properties in elastic metamaterials
advanced and efficient numerical methods are needed. The paper presents an extended …

This paper presents a study to accurately evaluate defects in concrete decks using
ultrasonic pulse-echo signals. A reinforced concrete deck with void defects was designed …

Optical field echo scattering characteristic is one of the essential technologies for the future
integration of underwater laser communication and detection. Vortex beam (eg Laguerre …
