Attenuation of Ultrasonic Guided Wave on Buried Illumination Pillar
2020 IEEE SENSORS, 2020This paper aims the development of a nondestructive inspection system for illumination pillars. The system detects the corrosion of a pillar by a screening inspection with a guided wave. Corrosion mainly occurs in the root part of the pillar in the ground. Small corrosion scatters and attenuates the guided wave.

Ultrasonics Guided Waves for Piping Inspection
1997An ultrasonic guided wave system for pipe inspection is proposed. Using guided wave experience to date on a variety of different tubing problems, feasibility experiments have already been conducted on piping under insulation in both a laboratory and chemical processing facility field environment. Several guided wave techniques are introduced, one using

Ultrasonic guided interface waves at a soft-stiff boundary
The Journal of the Acoustical Society of America, 2013Interface waves traveling along the boundary between two solids have been studied for nearly a century. However, little attention has been given to the case where interface waves travel at the boundary between a soft and stiff solid and when the soft material is relatively light and viscoelastic.

Ultrasonic Guided Waves in Solid Media
2014Ultrasonic guided waves in solid media have become a critically important subject in nondestructive testing and structural health monitoring, as new faster, more sensitive, and more economical ways of looking at materials and structures have become possible. This book will lead to fresh creative ideas for use in new inspection procedures.

Quantum Analogous Spin States of Ultrasonic Guided Waves
UltrasonicsIn quantum mechanics, spin is a physical property that dominates the topological behaviors. While manifesting the spin states they reveal complex interaction of physical parameters in a topological media. The guided waves' inherent spin states are made of real physical spin angular momentum from the superposition of elastic waves.

SH ultrasonic guided waves for the evaluation of interfacial adhesion
Ultrasonics, 2014Shear-Horizontally (SH) polarized, ultrasonic, guided wave modes are considered in order to infer changes in the adhesive properties at several interfaces located within an adhesive bond joining two metallic plates. Specific aluminium lap-joint samples were produced, with different adhesive properties at up to four interfaces when a glass-epoxy film is
