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.
