Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference between these component motions. The existence of Rayleigh waves was predicted in 1885 by Lord Rayleigh, after … WebMay 14, 2024 · Optical photons need to be polarized for optical Rayleigh to work. Look at your SteppingVerbose output–the photons are polarized but the particle weight is nonsense. Just as in Geant4 optical photons are different from gammas, the Rayleigh process for optical photons is different from the Rayleigh process for gammas.
