A parabolic wave equation approach for modeling propagation through windows

The work presents a novel method for studying wave propagation through windows based on the parabolic wave equation. A 2D wide-angle parabolic equation is applied for modeling of propagation through a set of windows. It is shown that the proposed method can be accurate and efficient in comparison with applying FDTD to the whole of the domain. Computer simulation results are presented for both normal and oblique incidence and compared with some reported results.
