Rayleigh's energy method
WebThe Rayleigh equation describing the angular distribution of resultant scattering is: [2]iθ/I0= { (n′/n)−1}2 (NV2/λ4r2) (1+cos2θ)where iθ is the intensity of light scattered at angle θ, I0 is … WebCommon-Offset Rayleigh Wave Method. This method is also called Common-Offset Surface Waves. The method is quite effective at mapping inhomogeneities in the near surface, although it is not a frequently used method. The field techniques are easy to apply, and compared to other seismic methods, it is a rapid technique.
