Web3. feb 2024 · We consider the general case of scattering from a homogeneous spherical particle with a background circularly polarized Gaussian field. The sphere is defined with a complex-valued refractive index n = n ̃ eiϕn (or susceptibility χ = n2 – 1 = χ̃ eiϕχ ). WebThe particle size of a spherical object can be unambiguously and quantitatively defined by its diameter. However, a typical material object is likely to be irregular in shape and non-spherical. The above quantitative definition of particle size cannot be applied to non-spherical particles.
