A Parabolic Equation Approach for Modeling Wave Propagation through Window Structures

In this paper, the parabolic equation method is applied to analyze radio wave propagation through window structures. By this method, a typical window propagation situation is simulated for different window sizes and frame types. The simulation results are represented for both normal and oblique incident cases of uniform and non-uniform plane wave. Results from the implementation of the parabolic equation method show good agreement with FDTD reported simulations. Base on this study, as the parabolic equation method needs less memory size and CPU time against FDTD method, it can be used as an efficient algorithm to analyze this kind of problems.
