lorenz_mie_coefs

lorenz_mie_coefs(radius_m, wavelength_m, n_p, n_med) ⇒ Float64Array

Implementation of Lorenz-Mie theory. Useful for calculating physically correct radiation scattering events for particles in a medium.

Kind: global function
Returns: Float64Array - Mie coefficients a_n and b_n in form [a_n0.r, a_n0.i, b_n0.r, b_n0.i, ... a_nN.r, a_nN.i, b_nN.r, b_nN.i]
