The estimation of the horizontal parameters of gravity waves by the monostatic Rayleigh Lidar
Scientific ReportsMonostatic Rayleigh Lidar is mainly used for the observation of the middle atmosphere temperature and vertical activity of gravity waves. It was thought that it could not be used for the study of the gravity waves horizontal activity.

Finite element simulations of surface effect on Rayleigh waves
AIP Advances, 2018 Rayleigh waves influenced by surface effect are investigated by using finite element methods, in which eigenfrequency analysis are performed on a model composed of a half-space covered by the surface effect dominated domain.

Near field enhancements from angled surface defects : a comparison of scanning laser source and scanning laser detection techniques [PDF]
, 2011 Enhancement of the Rayleigh wave signal amplitude at a surface defect, due to interference of incident, reflected and mode converted waves, has been reported by several authors, and it has been suggested that this could be used as a fingerprint of the ...

Defect feature extraction using surface wave interactions and time-frequency behavior [PDF]
, 2010 In this paper we exploit the interaction of ultrasonic surface waves with surface cracks in order to extract defect characteristics. An experimentally validated computer model was developed to simulate laser generated surface waves interacting with ...

Scanning laser source and scanning laser detection techniques for different surface crack geometries [PDF]
, 2012 Standard test samples typically contain simulated defects such as slots machined normal to the surface. However, real defects will not always propagate in this manner; for example, rolling contact fatigue on rails propagates at around 25ยบ to the surface,
