The Validation of the Simulated HIRF Effects in Metallic Cases Using Parallel FDTD Solver on a High Performance Computer

To accurately predict High Intensity Radiated Field (HIRF) effects in various systems is highly required for most commercial as well as defense applications, which is mainly based on electromagnetic simulation. Further, the validation of the simulated HIRF effects at different levels is also required. However, it is often difficult and needs some appropriate techniques and facilities. Here, in-house developed parallel Finite-Difference Time-Domain (FDTD) solver is at first employed for simulating the HIRF effects of two metallic cases with multiple slots and apertures, which is carried out on a high performance computer with tens of thousands of processors. The uncertainty analysis of the incident plane wave angle related to the electric field distribution in the metallic cases is finished with the help of non-intrusive polynomial chaos (NIPC) method, and the feature selective validation (FSV) is performed to quantify the difference between the measured and simulated field results. It is shown that the results obtained from the FSV method provide high reliability and confidence for our numerical characterization of HIRF effects in the metallic cases and even other complex structures.
