3D FE model of shielding textile materials

Due the previous work of the authors, the technical textile materials were successfully used as a protection against the undesirable external magnetic field. The woven textiles (compound of cotton, polyester, and conductive fibers) were analyzed before in 2D finite element environment. The mechanical (and electrical) structure of the material has been simplified as a 2D thin layer, and the simplification parameters have been set in comparison to measurement results. Recently, the latest results are presented in the paper, where the 2D model is extended to 3D space model, and a high-frequency analysis is provided. The obtained results are compared to 2D simulation (as well as to measurements) and discussed with particular attention paid to FE model and environment.
