Acceleration and Extension of Radial Point Interpolation Method (RPIM) to Complex Electromagnetic Structures

The computational performance of the radial point interpolation method (RPIM) is analyzed in highly discontinuous scenarios involving non-uniform grids as well as inhomogeneous media. A method of accelerating the RPIM simulation using domain decomposition on a high-performance computing (HPC) platform is additionally investigated. Our results indicate that RPIM may outperform FDTD where simulations of electrically large problems are concerned.
