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.

Cure monitoring using ultrasonic guided waves in wires
The Journal of the Acoustical Society of America, 2003The possibility of using ultrasonic guided waves for monitoring the cure process of epoxy resins is investigated. The two techniques presented use a wire waveguide which is partly embedded in the resin. The first technique is based on the measurement of attenuation due to leakage of bulk waves into the resin surrounding the waveguide.

Pipelines have advantages in fluid transportation, which play an important role in the rise of economy and social development. However, fouling in pipelines is an important issue that must be paid attention to by oil, gas, food and many other industries.

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.

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.
