Mie Scattering Technology

The Mie theory is a complete mathematical–physical theory of the scattering of electromagnetic wave by homogeneous spherical particles, developed by Gustav Mie in 1908. In contrast to Rayleigh scattering, the Mie theory embraces all possible ratios of the particle radius to wavelength. It relays upon the exact solution to Maxwell equation for spherical homogeneous obstacle with planewave excitation. The scattering intensity of Mie scattering is proportional to the square of the frequency, and the scattering is stronger in the forward direction of light than in the backward direction, and the directionality is more obvious.
