SA-PEEC formulation for lightning current modeling in conductive plates : a parametric analysis

This paper introduces an innovative approach to electromagnetic modeling based on the Partial Element Equivalent Circuit (PEEC) method, including an analytical integration of the coupling coefficients. A novel surface-based analytical formalism, termed SA-PEEC, is proposed to enhance computational efficiency and accuracy. The theoretical foundations of this method are detailed, highlighting its formulation and implementation. To demonstrate the versatility of the numerical model, various configurations are explored, including different material properties, positional arrangements, and computational domains. The results illustrate the adaptability and effectiveness of the SA-PEEC approach in modeling possible aircraft lighning-strike scenarios.
