Mie Scattering Theory The results of Mie theory indicate that the scattered light from the sphere can be considered to consist of partial waves radiated by multipoles formed by elec-tric charge constituting the sphere. A dipole ema-nates the ﬁrst partial wave, a quadrupole emanates the second, and so on. The amplitudes of the partial Fig. 1 compares Mie theory and Airy theory for the primary rainbow for x = 1000 and n 1.333.. Fig. 1 demonstrates that Airy theory provides a good approximation of the general features of the primary rainbow, such as the broad maximum around 139° and the maxima of the supernumerary arcs around 141.1°, 142.6° and so on. Mie theory is used, following the procedure described by Wiscombe. This code has been validated against his results.

Matzler's program mie.m utilizes his subroutine mie_abcd.m. The Mie solution for the light scattering of small spherical particles set the basis for more advanced scattering theories and today there are many methods to calculate light scattering and absorption for practically any shape and composition of particles. General approaches are now based on the Mie theory and the measurement of scattering intensity over a wide scattering angular range is employed. Additionally, non-laser light sources are often used to complement the main laser source to gain additional characteristic information about submicron-size particles . The Mie scattering theory is extremely complex and harder to understand than the Fraunhofer diffraction theory. This requires more complex programming and a fairly fast computer. It was for this reason that the Fraunhofer diffraction theory was only used in the past.

En optique ondulatoire, la théorie de Mie, ou solution de Mie, est une solution particulière des équations de Maxwell décrivant la diffusion élastique – c'est-à-dire sans changement de longueur d'onde – d'une onde électromagnétique plane par une particule sphérique caractérisée par son diamètre et son indice de réfraction complexe.

limit of geometric optics for large particles. Mie theory, therefore, may be used for describing most spherical particle scattering systems, including Rayleigh scattering.

The Mie theory is a theory of absorption and scattering of plane electromagnetic waves by uniform isotropic particles of the simplest form (sphere, infinite cylinder) which are in a uniform, isotropic dielectric infinite medium. Though the initial assumptions of the Mie theory are idealized its results are widely used when solving problems of radiation heat transfer in light scattering media. The Mie Theory. It wasn't until James Clerk Maxwell set forth the equations establishing the fundamental relationship between electricity and magnetism that a complete, rigorous theory of the scattering of light became possible. Today this theory is commonly known as Mie Theory, named after the 1908 treatise by the physicist Gustav Mie. particles.

There is also some biographic information on Gustav Mie, who published his famous paper on the colour of Gold colloids in 1908. The Mie solution for the light scattering of Se hela listan på de.wikipedia.org In this chapter the history and a review of the recent progress of Mie scattering and Mie-related light scattering theories and available computational programs is presented. We will focus on Mie scattering theories but as there is much overlap to related scattering theories they will also be mentioned where appropriate.

The Mie solution, also called Lorenz-Mie theory or Lorenz-Mie-Debye theory, provides an analytical solution of Maxwell’s equations for the scattering of electromagnetic radiation by spherical particles in terms of infinite series [1-3]. Scattering may be defined as the redirection of radiation from the original propagation direction

Mie scattering theory is the generalized solution that describes the scattering of an electromagnetic wave by a homogeneous spherical medium having RI different from that of the medium through which the wave is traversing. It is worth reiterating that Mie scattering is not any independent physical phenomenon. The Mie Theory. It wasn't until James Clerk Maxwell set forth the equations establishing the fundamental relationship between electricity and magnetism that a complete, rigorous theory of the scattering of light became possible. Today this theory is commonly known as Mie Theory, named after the 1908 treatise by the physicist Gustav Mie. This compensation is popularly termed “Mie Theory” which describes the effect of spherical shapes on light.
