Chess-board Acoustic Crystals with Momentum-space Nonsymmorphic Symmetries
Yanqiu Wang, Chen Zhang, Z. Y. Chen +3
Spatial symmetries appearing in both real and momentum space are of fundamental significance to crystals. However, in the conventional framework, every space group in real space, e…
A Weak Galerkin Mixed Finite Element Method for second order elliptic equations on 2D Curved Domains
Yi Liu, Wenbin Chen, Yanqiu Wang
This article concerns the weak Galerkin mixed finite element method (WG-MFEM) for second order elliptic equations on 2D domains with curved boundary. The Neumann boundary condition…
