Understanding the role of resonances and anti-resonances in shaping surface-wave bandgaps for metasurfaces.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 10/28/2022, Vol. 132 Issue 16, p1-14. 14p.

Abstract: An array of surface-mounted prismatic resonators in the path of Rayleigh wave propagation generates two distinct types of surface-wave bandgaps: longitudinal and flexural-resonance bandgaps, resulting from the hybridization of the Rayleigh wave with th...

Rayleigh wave and super-shear evanescent wave excited by laser-induced shock at a soft solid–liquid interface observed by photoelasticity imaging technique.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 3/28/2022, Vol. 131 Issue 12, p1-10. 10p.

Abstract: We investigated laser-induced shock excitation of elastic surface waves at a free surface and a soft solid–liquid interface using a custom-designed photoelasticity imaging technique. Epoxy-resin and pure water were selected as the solid and liquid medi...

A novel aseismic method using seismic metasurface design with mound structures.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 12/7/2021, Vol. 130 Issue 21, p1-10. 10p.

Abstract: We explore a seismic metasurface (SMS) design to control Rayleigh wave propagation for the earthquake resistance of critical buildings. An SMS is designed by assembling an array of soil mound units with different inclination angles to mold an accurate ...

Veering of Rayleigh–Lamb waves in orthorhombic materials.

Publication Type: Academic Journal

Source(s): Mathematics & Mechanics of Solids. Sep2022, Vol. 27 Issue 9, p1783-1799. 17p.

Abstract: We analyse veering of Rayleigh–Lamb waves propagating in a plane of elastic symmetry for a thin orthotropic plate. We demonstrate that veering results from interference of partial waves in a similar manner as it occurs in systems composed of one-dimens...

Eikonal Tomography With Physics‐Informed Neural Networks: Rayleigh Wave Phase Velocity in the Northeastern Margin of the Tibetan Plateau.

Publication Type: Academic Journal

Source(s): Geophysical Research Letters. 11/16/2022, Vol. 49 Issue 21, p1-9. 9p.

Abstract: We present a novel eikonal tomography approach using physics‐informed neural networks (PINNs) for Rayleigh wave phase velocities based on the eikonal equation. The PINN eikonal tomography (pinnET) neural network utilizes deep neural networks as univers...

Uniqueness, reconstruction and stability for an inverse problem of a semi-linear wave equation.

Publication Type: Academic Journal

Source(s): Journal of Differential Equations. Nov2022, Vol. 337, p395-435. 41p.

Abstract: We consider the recovery of a potential associated with a semi-linear wave equation on R n + 1 , n ≥ 1. We show that an unknown potential a (x , t) of the wave equation □ u + a u m = 0 can be recovered in a Hölder stable way from the map u | ∂ Ω × [ 0 ...

Rayleigh waves in nonpolar Al0.7Sc0.3N(112¯0) films with enhanced electromechanical coupling and quality factor.

Publication Type: Academic Journal

Source(s): Applied Physics Letters. 11/7/2022, Vol. 121 Issue 19, p1-5. 5p.

Abstract: This work reports on the growth of 1 µm nonpolar a-plane Al0.7Sc0.3N(11 2 ¯ 0) thin films on an r-plane sapphire Al2O3(1 1 ¯ 02) via magnetron sputter epitaxy. The electro-acoustic properties of the film structures were characterized using surface acou...

Analysis of reinforced soil wall for c–ϕ backfill considering Rayleigh wave.

Publication Type: Academic Journal

Source(s): Ground Improvement: Proceedings of the Institution of Civil Engineers. Nov2022, Vol. 175 Issue 4, p290-304. 15p.

Abstract: Analytical methods to analyse the seismic stability of reinforced soil walls showing the effect of Rayleigh waves are not available to date. In this study, the pseudo-dynamic approach was used to determine the seismic behaviour of a reinforced soil wal...
