Mie散射是诊断技术环境或自然环境中微粒或气溶胶粒子的重要工具。米氏理论仅限于球形、均匀、各向同性和非磁性粒子在非吸收介质中。然而，由于微粒几乎不可能是球形或均匀的，人们对更先进的散射理论很感兴趣。近几十年来，非球形和非均匀粒子的散射方法得到了发展，甚至有一些计算机代码。Mie理论的推广包括包覆球、层状球和团簇球。对于球面、椭球和有限圆柱等均匀非球形粒子，已经发展了表面离散化方法。非均匀粒子的散射可以用体积离散方法计算。
Mie scattering is an important tool for diagnosing microparticles or aerosol particles in technical or natural environments. Mie theory is restricted to spherical, homogeneous, isotropic and non-magnetic particles in a non-absorbing medium. However, as microparticles are hardly ever spherical or homogeneous, there is much interest in more advanced scattering theories. During recent decades, scattering methods for non-spherical and non-homogeneous particles have been developed and even some computer codes are readily available. Extension of Mie theory covers coated spheres, stratified spheres and clustered spheres. For homogeneous non-spherical particles such as spheroids, ellipsoids and finite cylinders, surface discretization methods have been developed. Scattering by inhomogeneous particles may be computed by volume discretization methods.
