Electromagnetic Wave Propagation Simulation by Meshless Time-Domain Method Embedding Modified RPIM-Based Shape Functions

摘要

To improve the performance of the Meshless Time-Domain Method (MTDM) for electromagnetic wave propagation simulations, a strategy for embedding the Modified Radial Point Interpolation Method (MRPIM)-based shape functions to the MTDM has been proposed. Numerical experiments show that the electric field determined by the MTDM embedding the MRPIM-based shape functions is smoothly distributed throughout a waveguide. In addition, the computational time of the MRPIM-based MTDM is always less than that of the conventional MTDM.
