Steady-state Diffusion theory

Examples

The following figures illustrate the transport of light from a steady-state isotropic point source of power within a homogeneous unbounded medium with absorption and scattering properties.

The simulation parameters for the medium are µ_a = 1.0 cm^-1, µ_s(1 - g) = 10.0 cm^-1, n_t = 1.33. The total impulse power is P_o = 1 W

The steady-state fluence rate F(r) is plotted versus r.

The C program that generated the data in the above figures is listed here.
