MATLAB codes Angular intensity distribution of single scattering The following MATLAB script calculates the angular distribution of the singly scattered intensity after the sequence ‘circular polarizer – spherical scatterer – circular polarizer’ in both backscattering setups, as derived in secs. 2.2 and 5.2.3. function mie_setup refractive_particle = 1.52 ; refractive_surround = 1.33 ; wavelength = 575e-9 ; diameter = 150e-6 ; % refractive index of the scatterer % refractive index of the surrounding medium % wavelength of the scattered light % particle diameter a = diameter / 2 ; m = refractive_particle / refractive_surround ; k = 2 * pi * refractive_surround / wavelength ; x = k * a ; angle = 180 : 0.01 : 181 ; theta = angle / 180 * pi ; mu = cos(theta) ; % or larger angular range for wide angle setup S1 = 0 ; S2 = 0 ; N = 50 + 1.03 * x ; N = fix (N) ; % avoids numerical overflow in Bessel functions for n = 1 : N A = J(n,m*x) ; B = J(n,x) ; C = dJ(n,x) ; D = dJ(n,m*x) ; E = H(n,x) ; F = dH(n,x) ; an = ( m * A * C - B * D ) / ( m * A * F - E * D ) ; bn = ( A * C - m * B * D ) / ( A * F - m * E * D ) ;
