Transverse Spurious Mode Compensation for AlN Lamb Wave Resonators
IEEE Access, 2019 Lamb wave modes with type I dispersion characteristics exhibit strong affinity toward multi transverse modes behavior above resonance frequency (fr) in the AlN Lamb wave resonators (LWRs), especially the high-transduction-efficiency modes: S0 and S1 mode.

Geophysical Research Letters, 2022 The 2022 volcanic eruption in Tonga caused an unusually large tsunami around the Pacific. It travels with a faster apparent velocity and has larger amplitudes at long distances than what would be expected from a conventional tsunami from the volcanic ...

Excitation of Lamb‐waves in plates [PDF]
PAMM, 2006 AbstractLamb waves show great potential in the detection of structural defects in plate and shell structures. In the sense of the adaptive structures concept the wave generation takes place with help of integrated piezoelectric ceramics. For a steel plate with adhered piezoelectric actuator, analytical calculations, FEM simulations, and experimental ...

The Suitability of Using 3D PLA Printed Wedges for Ultrasonic Wave Propagation
IEEE Access, 2020 This work studies the suitability of using 3D printed PLA wedges made through additive manufacturing to propagate Lamb waves in plate structures instead of using rather more expensive commercial wedges.
