Figure 5.

TD case: 〈z_max|t〉 (a) and (b) versus time. CW domain case: (c,d) 〈z_max|ρ〉 for different values of μ_a; (e,f) 〈z_max〉 and versus μ_a. The quantities were calculated both with DE (solid lines) and MC (dashed lines). In (e,f) also results of the DE solutions obtained placing the source at are reported (dotted lines). Panels (a,b) pertain to a semi-infinite diffusive medium and to a slab with s₀ = 20, 40 mm. Panels (c,e) pertain to a semi-infinite diffusive medium, while panels (d,f) pertain to a slab with s₀ = 20 mm. For all the panels we have and n_int = n_ext = 1.4.
