The application of the NIPC method and the FSV method on the validation of EM simulation under HIRF environment

Predicting the High Intensity Radiated Field (HIRF) coupling in complex system is highly required in the aeronautic industry, which can be performed by electromagnetic simulation. But the validation of electromagnetic simulation is a difficult issue which needs proper flowchart and validation methods. In this paper, the numerical simulation by the parallel Finite-Difference Time-Domain (FDTD) method is validated on a simplify model of a metallic case with apertures under the HIRF environment. Concretely, the uncertainty quantification analysis on the input parameter of incident angles is carried out for the electric field in the center of the model with the method of nonintrusive polynomial chaos (NIPC). Based on this, the feature selective validation (FSV) is performed to quantify the comparison of the experimental data and the best simulation estimate. And the results obtained from the FSV method provide a high reliability for the numerical simulation.
