Acesso em:.https://repositorio.ufpa.br/handle/2011/10110In this work, we use the two and three-dimensional versions of the finite-difference time-domain method, FDTD, for simulating the propagation of the electromagnetic waves in an indoor environment. First, the validity of the FDTD-3D method is proven by comparing the values of the power delay profile obtained via a measurement campaign carried out in the indoor environment. The losses expressed with the FDTD-3D method were used to propose corrections to the FDTD-2D results by taking into account the propagation in the free space and the propagation in the indoor environment. The advantages of the FDTD-2D method with corrected transient responses are reduced processing time and memory requirements when compared to other numerical methods. It is possible with the FDTD-2D with corrected signals to simulate wave propagation for large and complex environments and to develop simulation software for personal computers and mobile devices.Acesso AbertoOndas de rádio - propagaçãoOndas eletromagnéticas-simulaçãoDiferenças finitasTeseCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOESTELECOMUNICAÇÕES
