Multiple scattering by random configurations of circular cylinders: second-order corrections for the effective wavenumber.

C M Linton1, P A Martin.   

Abstract

A formula for the effective wavenumber in a dilute random array of identical scatterers in two dimensions is derived, based on Lax's quasicrystalline approximation. This formula replaces a widely-used expression due to Twersky, which is shown to be based on an inappropriate choice of pair-correlation function.
