Mie theory: Algorithms for functions of the scattering angle |
Prev topic | Next topic |
Recurrence-based calculations of the scattering angle-dependent coefficients πn and τn (see Mie theory: Overview) require no special algorithms to minimize the rounding error effects. Following Wiscombe (1996) or Wiscombe (1980), these coefficients can be efficiently calculated by the upward recurrence as follows:
| τn = nt - πn | (1) |
| πn+1 = s + t (n + 1) / n | (2) |
where s = cosθ πn and t = s - πn-1. The required initial values for πn are:
| π0 = 0 | (3a) |
| π1 = 1 | (3b) |
