Rayleigh phase

Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference between these component motions. The existence of … See more Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, … See more Rayleigh waves are widely used for materials characterization, to discover the mechanical and structural properties of the object being tested – like the presence of cracking, and the related shear modulus. This is in common with other types of surface … See more Low frequency (< 20 Hz) Rayleigh waves are inaudible, yet they can be detected by many mammals, birds, insects and spiders.

WebPhase change of Rayleigh scattering along a SMF can be measured in OFDR to provide distributed strain or temperature sensing with high spatial resolution and high accuracy. However, the polarization state (SOP) change in SMF will lead to failure of phase measurement in a traditional OFDR system. In this paper, OFDR with polarization diversity … WebThe Draine phase function tends to the Rayleigh phase function at long wavelengths and reduces to the phase function proposed by Cornette & Shanks[31] when = 1. A more sophisticated approach for modelling realistic phase functions can be established by assuming a particle size distribution and computing the ensemble average.
