Název v původním jazyce

Estimation of properties of homogeneous dielectric equivalent of composite shielding materials

Popis výsledku v původním jazyce

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 metal lattice and composite layers with metal lattice with a slot. 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 metal lattice in CST Microwave Studio is proposed focusing on a sufficient accuracy of the model. Second, two different approaches to homogenizing the composite with 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 walls.
