Fast boundary integral method for acoustic wave scattering in two-dimensional layered media
Linfeng Xia, Heng Yuan, Bo Wang +1
In this paper, we present a fast boundary integral method accelerated by the fast multipole method (FMM) for acoustic wave scattering governed by the scalar Helmholtz equation in m…
Fast multipole method for the Laplace equation in half plane with Robin boundary condition
Chunzhi Xiang, Bo Wang, Wenzhong Zhang +1
In this paper, we present a fast multipole method (FMM) for solving the two-dimensional Laplace equation in a half-plane with Robin boundary conditions. The method is based on a no…
Fast Multipole Method for Maxwell's Equations in Layered Media
Heng Yuan, Bo Wang, Wenzhong Zhang +1
We present a fast multipole method (FMM) for solving Maxwell's equations in three-dimensional (3-D) layered media, based on the magnetic vector potential under the…
Multi-scale DeepOnet (Mscale-DeepOnet) for Mitigating Spectral Bias in Learning High Frequency Operators of Oscillatory Functions
Bo Wang, Lizuo Liu, Wei Cai
In this paper, a multi-scale DeepOnet (Mscale-DeepOnet) is proposed to reduce the spectral bias of the DeepOnet in learning high-frequency mapping between highly oscillatory functi…
