Figure 4

Deviation function with Mie effects fully taken into account.
We choose θ = π and three different sets of scattering angles ϕ1,2 = 90° + δϕ1,2. The black, red and blue curves correspond to (δϕ1, δϕ2) = (−12°, 7°), (−15°, 5°) and (−9°, 9°), respectively. (a) |Δα|/α as a function of the size parameter x with ε = 30 fixed. (b) |Δα|/α as a function of the bulk dielectric constant ε with x = 0.01 fixed. The circles show the corresponding numerical results (COMSOL Multi-physics).
