Multiple Scattering Theory in a General Basis

  • We present a theory to describe multiple scattering (MS) with an arbitrary basis. This framework allows us to select a set of new basis that exhibits better convergent properties than the usual spherical wave basis. Therefore, it enables us to perform faster and less memory-consuming calculations. Although the method outlined here is quite general, it gives a better description of the scattering properties and consequently reduces the size of the two block matrices involved in the MS calculation.

Abstract: We present a theory to describe multiple scattering (MS) with an arbitrary basis. This framework allows us to select a set of new basis that exhibits better convergent properties than the usual spherical wave basis. Therefore, it enables us to perform faster and less memory-consuming calculations. Although the method outlined here is quite general, it gives a better description of the scattering properties and consequently reduces the size of the two block matrices involved in the MS calculation.
