Scatterer models and their parameters

This page will contain brief descriptions (incl. refs) and parameter lists for most popular models of small scattering particles used in applications.

single particle:
- homogeneous particles:
  - sphere - m, r
  - infinite cylinder - m, r, alpha
  - finite cylinder - m, r, l, alpha
  - spheroid - m, a, b, alpha
  - ellipsoid - m, a, b, c, alpha, beta
  - Chebyshev particle - m, r, n, eps, alpha
  - more complex:
    - irregular surface ...
    - bi-sphere - m, r, ...
    - multi-sphere - ...
    - fractal aggregate - ...
- inhomogeneous particles:
  - core/mantle:
    - sphere - m1, m2, r1, r2
    - infinite cylinder - m1, m2, r1, r2, alpha
    - spheroid - m1, m2, a1, b1, a2, alpha
  - multi-layered:
    - sphere - {m}, {r}, orientation
  - small/large inclusions:
    - ...
ensemble of particles:
- averaging over orientations - types of alignment, distributions (formulas + refs)
- averaging over size - types of distributions (formulas + refs)

Note that the parameters include the incident radiation wavelength as well as its polarization.
