Abstract-The plane wave diffraction by a terminated semi infinite parallel-plate waveguide with two-layer material loading and impedance boundaries is rigorously analyzed for E polarization using the Wiener-Hopf technique. Introducing the Fourier transform for the scattered field and applying boundary conditions in the transform domain, the problem is formulated in terms of the simultaneous Wiener-Hopf equations, which are solved via the factorization and decomposition procedure.The scattered field is evaluated by taking the inverse Fourier transform and applying the saddle point method. The numerical examples of the radar cross section (RCS) are represented for various physical parameters and backscattering characteristics, of considered geometry for open ended cavity and discussed in detail.

“…As a related cavity geometry a terminated, semi-infinite parallel plate waveguide with three-layer material loading with perfectly conducting walls has been analyzed in [12] through the Wiener-Hopf technique. This problem has later on generalized for empty cavities having imperfectly conducting walls [11].…”

“…There are some papers treating cavity diffraction problems based on the WienerHopf technique [17,18], where efficient approximate solutions have been obtained. In the previous papers [19][20][21][22][23], we have considered several 2-D cavities formed by semi-infinite and finite parallel-plate waveguides, and analyzed the plane wave diffraction rigorously by using the Wiener-Hopf technique.…”

Abstract-The plane wave diffraction by a finite parallel-plate waveguide with four-layer material loading is rigorously analyzed for the case of E polarization using the Wiener-Hopf technique. Introducing the Fourier transform for the scattered field and applying boundary conditions in the transform domain, the problem is formulated in terms of the simultaneous Wiener-Hopf equations, which are solved via the factorization and decomposition procedure together with a rigorous asymptotics. The scattered field is evaluated explicitly by taking the inverse Fourier transform and applying the saddle point method. Representative numerical examples of the radar cross section (RCS) are shown for various physical parameters and the far field scattering characteristics are discussed in detail.

“…It appears, however, that the solutions obtained by these approaches are not uniformly valid for arbitrary cavity dimensions. There are also important contributions to studies on the cavity RCS based on a rigorous function-theoretic approach based on the Wiener-Hopf technique [14,15].…”

Abstract-The plane wave diffraction by a terminated, semi-infinite parallel-plate waveguide with four-layer material loading is rigorously analyzed using the Wiener-Hopf technique. Introducing the Fourier transform for the unknown scattered field and applying boundary conditions in the transform domain, the problem is formulated in terms of the simultaneous Wiener-Hopf equations satisfied by the unknown spectral functions. The Wiener-Hopf equations are solved via the factorization and decomposition procedure leading to the exact solution. The scattered field in the real space is evaluated by taking the inverse Fourier transform and using the saddle point method.Representative numerical examples of the radar cross section (RCS) are presented, and the far-field scattering characteristics of the waveguide are investigated in detail.
