This paper discusses some implementation details in accelerating physical optics - shooting and bouncing rays (POSBR) method using graphics processing unit (GPU). Compute unified device architecture (CUDA) and OptiX from Nvidia are used to reduce computational time of monostatic scattering pattern prediction of electrically large arbitrary target.
Benchmark results for electromagnetic scattering from large cavity structures are very important in developing efficient simulation tools for real cavity design. This paper focuses how to apply our in-house parallel higher order finite element-boundary integral (FE-BI) code to efficiently simulate EM scattering from large cavities. The results obtained can serve as benchmark data with very good accuracy...
Several key implementation measures are proposed for effectively mapping the shooting and bouncing rays-physical optics (SBR-PO) method to a graphics processing unit (GPU) to accelerate the solution process of scattering problems. Compute unified device architecture (CUDA) and OptiX from NVIDIA are used to reduce computational time for the modeling of monostatic scattering from electrically large...
This paper will discuss how to combine the preconditioned FE-BI-DDM matrix equation with the help of the reverse Cuthill-McKee (RCM) algorithm, ILU decomposition, and fast algorithm for matrix-vector multiplication in GMRES solver into a powerful method for modeling and understanding the scattering characteristics of cavity within a general body. Numerical results obtained using the proposed method...
