Rayleigh scattering regime
WebDec 6, 2024 · Measurements are conducted on stainless steel at different ultrasonic frequencies (all in the Rayleigh scattering regime). The non-paraxial sound field model is used here to eliminate the diffraction loss and to obtain the total attenuation. Experimental results verify that LRWs have very little velocity dispersion. WebRayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 110 the wavelength of the …

WebRayleigh scattering can be defined as scattering in the small size parameter regime x ≪ 1. Scattering from larger particles is explained by the Mie scattering for an arbitrary size parameter x. For small x the Mie theory reduces to the Rayleigh approximation. It can be seen from the above equation that Rayleigh scattering is strongly ... WebIn this work, the radiation force on a Rayleigh dielectric particle induced by the partially coherent circular Airy beam (PCCAB) is investigated. Our numerical results show that the PCCAB can be used to trap and manipulate particles. The radiation force distribution and trapping stability have been analyzed under different coherent lengths. It is found that, …
