Accelerated SBR Method Based on MPI for Electromagnetic Scattering Problems

This paper presents a method called Shooting and Bouncing Rays (SBR) employing the Message Passing Interface (MPI) to address electromagnetic scattering issues arising from complex and electrically large targets. The accuracy of the proposed method has been validated by comparing the simulated results with those obtained from the multilevel fast multipole method (MLFMM). And a good speedup ratio has been achieved for SBR with MPI.
