Incoherent vs coherent scattering

http://ncnr.nist.gov/resources/sldcalc.html WebMay 8, 2007 · 7 provides an intuitive means for comparing the efficiencies of coherent vs. incoherent processes. Its physical interpretation is very clear: at maximal coherence (ρ bc = 1/2) the ratio of those efficiencies roughly equals to the total number of molecules (counted through the sample thickness) per λ 2 area (where λ is the wavelength of ...

WebApr 23, 2016 · In incoherent scattering, the phase-shift between the incident plane wave and the scattered spherical wave for each nucleus is random. As in coherent scattering, each nucleus is the point source of a spherical wave, and the array of point sources creates a family of spherical waves that superpose. WebMay 1, 2001 · If both incoherent and coherent scattering contribute to the return, the measured difference should lie somewhere between 0 dBZ and the value predicted by Eq. (18). This happens, for example, when the radar return at the longer wavelength is dominated by coherent scattering from humidity and temperature variations and the … css dark scrollbar https://mrhaccounts.com
