discrete dipole approximation

The validity criteria of the discrete dipole approximation have been recently revised.

This article contains list of discrete dipole approximation codes and their applications.

The compilation contains information about the discrete dipole approximation, relevant links, and their applications.

For non-spherical particles one could use discrete dipole approximation or other methods of computational electromagnetics.

Discrete dipole approximation, method for computing scattering of radiation by particles of arbitrary shape.

A popular alternative for this is the Discrete dipole approximation (DDA) method.

The discrete dipole approximation is a flexible technique for computing scattering and absorption by targets of arbitrary geometry.

The discrete dipole approximation is an approximation of the continuum target by a finite array of polarizable points.

They distributed discrete dipole approximation open source code DDSCAT.

Scattering by particles similar to or larger than the wavelength of light is typically treated by the Mie theory, the discrete dipole approximation and other computational techniques.

They are listed as discrete dipole approximation codes, codes for electromagnetic scattering by cylinders, codes for electromagnetic scattering by spheres.

The approximation of a medium or an array of charges by only dipoles and their associated dipole moment density is sometimes called the point dipole approximation, the discrete dipole approximation, or simply the dipole approximation.

Even though Mie theory offers convenient and fast way of solving light scattering problem by homogeneous spherical particles, there are other techniques, such as discrete dipole approximation, FDTD, T-matrix, which can also be used for such tasks.

He is one the authors (together with Piotr J. Flatau) of the public domain DDSCAT code based on the discrete dipole approximation approximation which has application to light scattering by non-spherical particles and nanophotonics.
