_S1_S2_nb

miepython.mie_jit._S1_S2_nb(m, x, mu, n_pole)

Calculate the scattering amplitude functions for spheres.

The amplitude functions have been normalized so that when integrated over all 4*pi solid angles, the integral will be qext*pi*x**2.

The units are weird, sr**(-0.5)

Parameters:

• m – the complex index of refraction of the sphere

• x – the size parameter of the sphere

• mu – array of angles, cos(theta), to calculate scattering amplitudes

• n_pole – return n_pole term from series (default=0 means include all terms)

Returns:

S1, S2 – the scattering amplitudes at each angle mu [sr**(-0.5)]
