Non-Intrusive Polynomial Chaos Methods and its Application in Verification and Validation of Electromagnetic Models

A quantification analysis method was studied to verify and validate the electromagnetic models in this paper. Concretely, the non-intrusive polynomial chaos method was used to analyze the uncertainty response quantification of the simulation outcomes caused by the uncertainty input parameters of electromagnetic model. Based on the arithmetic and main procedures analyses, numerical experiment results confirm that the proposed method can be taken as a valuable tool to simulate the propagation of uncertainties and uncertainty quantification for electromagnetic models. Finally, taking a metallic crate with apertures as the electromagnetic model, the effect of uncertainty quantification of the incident angle input parameter on the electric field in the center of the mode was analyzed with the proposed method. Then the feature selective validation (FSV) was used to compare and evaluate the experimental and optimal simulation data, forming the evaluation grade.
