Item Acesso aberto (Open Access) Análise de propagação de ondas eletromagnéticas em ambiente indoor: modelo do caminho dominante versus traçado de raios e FDTD(Universidade Federal do Pará, 2011-03-11) LIMA, Bruno Wallacy Martins; DMITRIEV, Victor Alexandrovich; http://lattes.cnpq.br/0684541646225359This work deals with some models propagation of electromagnetic waves. Were first analyzed models related to the prediction signal electromagnetic indoor environments. The models used in this work were the ray tracing, path dominant Energy (DPM) and the FDTD. For the first two models we used commercial software and the FDTD method was developed an algorithm for which the signal is analyzed in an environment with the same geometry used software. The results for the reception points analysis provided by the three models are very close the values of literature. There is the influence of propagation phenomena in signal strength. The relevance of this work is in fact not there, in the literature, studies that compare the three prediction models mentioned, and to propose topics for future research.
