Summary: | To rapidly capture the electromagnetic scattering behavior of electrically large and complex structures, we have developed a hybrid high frequency (HF) simulation tool through the combination of different asymptotic methods, such as physical optics (PO), shooting and bouncing rays (SBR), and physical theory of diffraction (PTD). Careful consideration of integrating PO, PTD, and SBR together ensures good accuracy of the hybrid HF tool. Effective implementation of the hybrid HF tool with using the state of the art GPU and CPU high performance computing (HPC) techniques greatly speeds up the solution process of modeling backscattering from electrically large and complex objects for rapid design. It should be noted that, differing from fast full wave simulation methods, the hybrid HF simulation tool uses different HF technique to handle different scattering wave component to understand its underlying physics and effects on total scattering responses, which is very important for complex structure design. |
