Item Acesso aberto (Open Access) Modelo para representação de ambientes 3D utilizando composição de modos do método FDTD-2D(Universidade Federal do Pará, 2017-05-26) LIMA, Bruno Wallacy Martins; DMITRIEV, Victor Alexandrovich; http://lattes.cnpq.br/3139536479960191In 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.
