Contactless estimation of soil moisture using leaky Rayleigh waves and a fully convolutional network
Vadose Zone Journal, 2023 Soil moisture is a key factor that influences various aspects of ecosystem functioning. Measuring soil moisture without installing any objects in the soil is desirable because it allows for accurate characterizations of soil moisture while minimizing ...

Bulk and Rayleigh Waves Propagation in Three-Phase Soil with Flow-Independent Viscosity
Applied Sciences, 2022 The flow-independent viscosity of the soil skeleton has significant influence on the elastic wave propagation in soils. This work studied the bulk and Rayleigh waves propagation in three-phase viscoelastic soil by considering the contribution of the flow-

Multiple wavemode scanning for near and far-side defect characterisation [PDF]
, 2020 The combination of ultrasonic inspections using different wavemodes can give more information than is available with single mode inspection. In this work, the response of shear and Rayleigh waves to surface-breaking defects propagating on the near-side ...

Viscoelastic Rayleigh waves II [PDF]
Quarterly of Applied Mathematics, 1978 The number of possible surface waves on a viscoelastic half-space is investigated numerically as a function of the material parameters. The results are applied to simple theoretical models of viscoelastic behavior and also to experimental data. It is concluded that two surface waves are possible on some rocks and on nearly all solid polymers.

Anomalous surface waves from Lop Nor nuclear explosions: Observations and numerical modeling [PDF]
, 1998 Surface waves from the Chinese test site of Lop Nor are analyzed using long-period and broadband stations located at regional and teleseismic distances and at different azimuths. For most azimuths, strong Love waves between 0.02 and 0.045 Hz are observed

Rayleigh–Taylor shock waves [PDF]
Physics of Fluids, 2007 Beginning from a state of hydrostatic equilibrium, in which a heavy gas rests atop a light gas in a constant gravitational field, Rayleigh–Taylor instability at the interface will launch a shock wave into the upper fluid. We have performed a series of large-eddy simulations which suggest that the rising bubbles of light fluid act like pistons ...

Disturbances of surface wave field due to wave scattering at shallow cavities
Yantu gongcheng xuebao, 2018 In homogenous half spaces, the wave fields at shallow depth are dominated by Rayleigh waves activated by the surface sources. When the forward Rayleigh waves encounter a shallow cavity, the displacement shapes and the particle orbit are changed. Rayleigh
