Coherent Potential Approximation

From Wikipedia, the free encyclopedia

In Physics the Coherent Potential Approximation commonly referred to simply as the CPA is a method to find the Green function of an effective medium. The CPA is a useful concept in understanding how waves scatter in a material which displays spatial inhomogeneity.
