Web8.8.2 Scattering Coefficient. The scattering coefficient is, by default, set to zero, and it is assumed to be isotropic. You can specify a constant value, a temperature-dependent function (see Section 8.2), or a user-defined function. You can also specify a non-isotropic phase function. The scattering coefficient is requested in units of 1/length. WebThe mass attenuation coefficient is defined as: μ m = η A σ tot/ ρ. where ρ is the density of the material. Figure 2 shows the mass attenuation coefficient of the silicon with the indication of its different components. Figure 2 …
