An Adaptive Finite Element DtN Method for the Acoustic-Elastic Interaction Problem in Periodic Structures
Lei Lin, Junliang Lv
Consider a time-harmonic acoustic plane wave incident onto an elastic body with an unbounded periodic surface. The medium above the surface is supposed to be filled with a homogene…

Alternately-optimized SNN method for acoustic scattering problem in unbounded domain
Haoming Song, Zhiqiang Sheng, Dong Wang +1
In this paper, we propose a novel machine learning-based method to solve the acoustic scattering problem in unbounded domain. We first employ the Dirichlet-to-Neumann (DtN) operato…
