Acesso em:.https://repositorio.ufpa.br/handle/2011/2614This 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.porAcesso AbertoEficiência de blindagemMétodo FDTDFormulação de sub-célulaParedes finasElectromagnetic shielding efficiencyFDTD methodSub-cellular formulationThin steel wallsDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES
