Fig. 4. Effect of the phase shift parameter, ρ, at a fixed wavelength (0.55 µm in air) on M₁₁ element of the scattering matrix of a microsphere according to Mie theory. Here, the M₁₁ element at a scattering angle of 60° is shown as an efficiency, i.e. it is divided by the microsphere cross section area, for a spherical seawater droplet in air (light blue curve, salinity of 35.5, relative refractive index, m = 1.343 - 0i, Δx ~ 0.1), a spherical air bubble in seawater (oscillating gray curve, m = 0.745, Δx ~ 1), and a voidless carbon sphere in air (smooth black curve, m = 1.95 - 0.79i, Δx varies from 0.01 to 1). All efficiencies were calculated with the MJC Light Scattering Calculator for Homogeneous Spheres. Plotting the efficiencies as functions of the phase shift parameter does not align the dominant oscillations unlike in the case of the attenuation efficiency and absorption efficiency (Fig. 3).
