Item Acesso aberto (Open Access) Análise da eficiência de blindagem de estruturas indoors construídas com lâminas "finas" condutoras elétricas, através do método FDTD(Universidade Federal do Pará, 2009-09-25) ROCHA, Rita de Cássia Florêncio; SOUZA SOBRINHO, Carlos Leônidas da Silva; http://lattes.cnpq.br/1450994881555781This work presents results regarding electromagnetic shielding structures using thin conductive sheets. The simulations were performed by using the finite difference time domain method (FDTD), in which a sub-cellular formulation has been implemented for modeling thin steel walls. The implementation was validated via comparison of the obtained results to those available in the literature. Then, several geometries were tested, including apertures on the structures and by changing the space between double shielding walls. Finally, a complete high-voltage laboratory was simulated (by analyzing the shielding efficiency) considering a closed structure and apertures.
