Discrete dipole approximation codes

This article contains list of discrete dipole approximation codes and their applications.
The discrete dipole approximation
(DDA) is a flexible technique for computing scattering and absorption by targets of arbitrary geometry. Given a target of arbitrary geometry, one seeks to calculate its scattering and absorption properties. The DDA is an approximation of the continuum target by a finite array of polarizable points. The points acquire dipole moments in response to the local electric field. The dipoles of course interact with one another via their electric fields, so the DDA is also sometimes referred to as the coupled dipole approximation. It is closely related to method of moments, digitized Green's function, volume integral method.
, relevant links, and their applications. There are reviews
as well as published comparison of existing codes.
