Analysis of a Fast Method for Accelerating the Evaluation of 3D Doubly Periodic Function
This paper describes a hybrid Ewald method to accelerate the calculation of three-dimensional double-PGF by changing the calculation formula of different sampling regions of the three-dimensional two-period Green's function.The numerical results show that the hybrid Ewald method has higher computational efficiency than the Ewald method.At the same time,this method is also suitable for Green's function calculations with exponential decay in either direction.
