Ultrasonic Lamb Waves for Wireless Power Transfer

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2020
Ultrasonic guided plate waves (Lamb waves) can be used to transfer power along the length of metal plates, achieving longer distance wireless power transfer (WPT), while not being impeded by electromagnetic shielding from the metal plate. In this article, a fundamental study on the performance of Lamb wave WPT is presented, including modeling ...

Ultrasonic Lamb wave diffraction tomography

Ultrasonics, 2001
Ultrasonic guided waves, Lamb waves, allow large sections of aircraft structures to be rapidly inspected. Unlike conventional ultrasonic C-scan imaging that requires access to the whole inspected area, tomographic algorithms work with data collected over the perimeter.

Lamb Wave Multitouch Ultrasonic Touchscreen

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016
Touchscreen sensors are widely used in many devices such as smart phones, tablets, and laptops with diverse applications. We present the design, analysis, and implementation of an ultrasonic touchscreen system that utilizes the interaction of transient Lamb waves with objects in contact with the screen. It attempts to improve on the existing ultrasound

Ultrasonic Lamb wave tomography

Inverse Problems, 2002
The ultrasonic Lamb wave tomography is considered in the frame of the pressing nondestructive evaluation (NDE) technology need. The work focuses on tomographic reconstruction to produce quantitative maps that can be easily interpreted by technicians or fed directly into structural integrity and lifetime prediction codes.

Ultrasonic Lamb wave inspection of composite defects

Health Monitoring of Structural and Biological Systems IX, 2020
Composites have been extensively used in aerospace engineering due to their advantages of light weight, high strength, and engineering design flexibility. Manufacturing defects such as wrinkle and porosity can affect the performance of the composites and may lead to failure in the end, while damage such as delamination, fiber fraction, and matrix ...

Liquid level sensor using ultrasonic Lamb waves

Ultrasonics, 2003
This paper describes a novel, noninvasive method for measurement of liquid level in closed metal tanks that are under high pressure. It is based on the use of ultrasonic Lamb waves propagating along the tank wall. Contact with liquid substantially changes the characteristics of these waves and this can be used as an indicator of liquid presence ...
