Hybrid reliability analysis method for electromagnetic design problems with non-Gaussian probabilistic parameters

This paper proposes an efficient and stable reliability analysis method for electromagnetic (EM) design problems with non-normal probability distributions of input parameters. A hybrid search algorithm for a most probable failure point (MPP) is introduced to assess the reliability of highly nonlinear constraint functions. The proposed method is tested with a loudspeaker design, of which random variables follow five different probability distributions case by case.
