Original Abstract
The paper is focused on numerical studies of electromagnetic properties of composite materials used for the construction of small airplanes. Discussions concentrate on the homogenization of composite layers with a metal lattice. The homogenization is aimed to reduce CPU-time demands of EMC computational models of electrically large airplanes. First, a methodology of creating a 3-dimensional numerical model of a composite material with a metal lattice with different degree of detail in CST Microwave Studio is proposed focusing on a sufficient accuracy of the model. Second, single-objective and multi-objective approaches to the homogenizing the composite material with a metal lattice are discussed. The proposed approaches are evaluated and compared from the viewpoint of the efficiency, the accuracy, the convergence, and hardware requirements. The obtained field distribution is compared with the distribution computed for the original composite material.
