Dispersion analysis of the meshfree radial point interpolation method for the Helmholtz equation

When numerical methods such as the finite element method (FEM) are used to solve the Helmholtz equation, the solutions suffer from the so‐called pollution effect which leads to inaccurate results, especially for high wave numbers. The main reason for this is that the wave number of the numerical sol...
