Beam diffraction effects in guided-wave transmission of fluid embedded elastic plate. Influence of receiver distance and finite aperture.

Midtbø, Simen Hammervold (Master thesis, 2018-06-23)

For the past decades, plate transmission effects have been extensively studied with the incentive of applying the knowledge in GUW methods in the industry. With these studies, multiple anomalous effects have been identified, ...
Interaction of three-dimensional acoustic beam with fluid-loaded solid plate: Axial near- to far-field transmission at normal beam incidence

Sæther, Mathias Myrtveit; Midtbø, Simen Hammervold; Lunde, Per (Journal article; Peer reviewed, 2022)

Axial radiation from leaky Lamb waves propagating in a 6.05 mm water-immersed steel plate being excited by a sound beam normally incident to the plate, is investigated as a function of axial distance, z, and frequency, f, ...
