  • Shangpan Wang,
  • Zhichao Xiang and
  • Guanjun Zhang

30 March 2023

The traditional finite element method (FEM) could only provide acceptable numerical solutions for the Helmholtz equation in the relatively small wave number range due to numerical dispersion errors. For the relatively large wave numbers, the correspo...
