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 …

Characterizing cracks within elastic media forms an important aspect of ultrasonic non-
destructive evaluation (NDE) where techniques such as time-of-flight diffraction and pulse …

The nonlinear guided wave technique based on contact acoustic nonlinearity (CAN) has
been considered one of the best approaches for characterizing microcracks or fatigue cracks …

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 …

In non-destructive evaluation guided wave inspections, the elastic structure to be inspected
is often embedded within other elastic media and the ensuing leaky waves are complex and …

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 …

The ability to design surfaces with specific scattering properties has widespread
applicability. In this article, we leverage a stochastic method for designing randomly rough …

Ultrasonic is one of the well-known methods for surface roughness measurement, but small
roughness will only lead to a subtle variation of transmission or reflection. To explore …

The miniaturization, ultra-thin and multi-layer complex structure of microelectronic packaging
complicates the coupling acoustic field of ultrasonic waves and internal defects in the …
