Rayleigh effect
WebDec 30, 2024 · The Rayleigh damping model is an approximation to viscous damping available in Harmonic and Dynamic FEA simulations. It allows modeling the energy dissipation in the material due to internal friction, assuming it is proportional to the strain or deformation rate. As such, it is common to be in the need to determine the model … WebSep 1, 2000 · Frequency spectrum of coherent Rayleigh scattering from N 2 at 6.6 kPa (50 torr) and 298 K.

WebLord Rayleigh was the first to deal with scattering of light by air molecules. The scattering of sunlight by the molecules of the gases in Earth’s atmosphere is called Rayleigh scattering. The basic process in scattering is absorption of light by the molecules followed by its re-radiation in different directions. WebMar 1, 1981 · The acoustoelastic effect is investigated for the Rayleigh surface wave propagating in a homogeneous isotropic material. The initial deformations considered are uniform and nonuniform only in the direction of depth. The formulas for the velocity change versus the change in the applied static stress are derived in the first-order approximation. …
WebThe backscattering from an EDFA exceeds backscattering from an equivalent length of a non-doped fiber. Because Rayleigh backscattering can cause degradation in the EDFA performance [1], this effect has to be considered in the simulations to give better accuracy in the results. The EDF component considers the Rayleigh scattering effect in the ... WebFeb 25, 2024 · This behavior can be attributed to a reduced collective effect, which can be explained by the fact that in this period range, the Rayleigh anomalies are no more excited following the direction of ...
WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to … WebRayleigh scattering (pronounced /ˈreɪli/ RAY-lee), named after the British physicist Lord Rayleigh (John William Strutt), is the (dominantly) elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. The Rayleigh scattering does not change the state of material hence it is a parametric …
WebRayleigh damping does afford certain mathematical conveniences and is widely used to model internal structural damping. ... This effect is strongly amplitude dependent and is poorly represented by Rayleigh damping. The …
WebDebye or Mie is an elastic scattering mechanism which occurs from relatively large particles or molecules with dimensions comparable with the wavelength of the incident radiation, or larger, and the resulting scattered radiation is non-uniform. The effect is not very wavelength dependent. This process gives rise to the white scattered light ... incentea wallWebThe key contributions of the four great Nobel Laureates – Lord Rayleigh, Sir William Ramsay, Lord Rutherford and Sir Chandrasekhara Raman – to the understanding of light scattering, to the identification and classification of the rare gases, and to the discovery in 1928 of the Raman effect are outlined.
