ICECom 2003-electromagnetic scattering analysis in indoor and outdoor environments by applying FDTD method

Economical and efficient means to obtain the characterization of radio channels have been investigated a lot since mobile communication devices became popular. So, this article presents solutions and results for two electromagnetic scattering problems: an outdoor environment simulation, solved by applying the two-dimensional FDTD formulation and an indoor environment radiation scattering simulation, whose solution was based on the three-dimensional FDTD formulation. In both cases, the numerical domains were truncated by using the UPML formulation and solved through code parallelization techniques. Power received at specific points and field distribution are analyzed.
