Surface profile recovery from electromagnetic field with physics--informed neural networks
Yuxuan Chen, Ce Wang, Yuan Hui +1
Physics--informed neural networks (PINN) have shown their potential in solving both direct and inverse problems of partial differential equations. In this paper, we introduce a PIN…

Multigrid on unstructured meshes with regions of low quality cells
Yuxuan Chen, Garth N. Wells
The convergence of multigrid methods degrades significantly if a small number of low quality cells are present in a finite element mesh, and this can be a barrier to the efficient…

Reconstruction of rough surfaces from a single receiver at grazing angle
Yuxuan Chen, Mark Spivack, Orsola Rath Spivack
The paper develops a method for recovering a one-dimensional rough surface profile from scattered wave field, using a single receiver and repeated measurements when the surface is…
