中文百科

米氏散射

米式散射(Mie scattering),是一种光学现象,属于散射的一种情况。米式散射理论是由德国物理学家古斯塔夫·米于1908年提出的。

当微粒半径的大小接近于或者大于入射光线的波长λ的时候,大部分的入射光线会沿着前进的方向进行散射,这种现象被称为米式散射。这种大微粒包括灰尘,水滴,来自污染物的颗粒物质,如烟雾,等等。

Mie scattering 米氏散射

Monostatic radar cross section [RCS] of a perfectly conducting metal sphere as a function of frequency (calculated by Mie theory). In the low frequency Rayleigh scattering limit where the circumference is less than the wavelength, the normalized RCS is σ/(πR2) ~ 9(kR)4. In the high frequency optical limit σ/(πR2) ~ 1
The change of sky colour at sunset (red nearest the sun, blue furthest away) is caused by Rayleigh scattering by atmospheric gas particles which are much smaller than the wavelengths of visible light. The grey/white colour of the clouds is caused by Mie scattering by water droplets which are of a comparable size to the wavelengths of visible light.

The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous sphere. The solution takes the form of an infinite series of spherical multipole partial waves. It is named after Gustav Mie.
