Abstract :
In this paper transmission line matrix method is used to simulate the wave propagation through window structures. In this analysis a single window with precise dimensions and also a group of windows are considered. The effect of window’s dimension, window’s material, and angle of incidence are all evaluated in details and in each case, the method has been compared with other numerical results, such as FDTD, ray tracing, and finite element methods. Furthermore, in one case the implementation of TLM method was shown to have a good agreement with the measured values.
