TL;DR: A new version of the fast multipole method (FMM) for screened Coulomb interactions in three dimensions relies on an expansion in evanescent plane waves, with which the amount of work can be reduced to 40p2 + 6p3 operations per box.

TL;DR: In this article, the authors describe a new approach to the imposition of exact nonreflecting boundary conditions for the scalar wave equation, and compare the performance of their approach with that of existing methods by coupling the boundary conditions to finite-difference schemes.
