Rayleigh scattering regime
WebScattering and interference of waves in plasmonic nanostructures can be exploited for improved performance in various applications. They often rely on other optical processes, such as plasmon hybridization, which involves the coupling between plasmons in different nanostructures, and Fano resonance, which arises from the interference between a … http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf

WebMultiple scattering of polarized electromagnetic waves in diffusive media is investigated by means of radiative transfer theory. This approach amounts to summing the ladder diagrams for the diffuse reflected or transmitted intensity, or the cyclical ones for the cone of enhanced backscattering. The method becomes exact in several situations of interest, … 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.
