“…We also see that for negative h, the peak location gradually shifts from the incident shadow boundary at À1208, with an increase of kb. Figure 3 shows comparison of the results for kb ¼ 0:01 and kb ¼ 0 (a slit in an infinite, perfectly conducting plane [11,12]) for E polarization ka ¼ 10, h 0 ¼ 608. We observe that the two curves become very close to each other, as expected.…”

The diffraction by a slit formed by two semi-infinite parallel-plate waveguides is rigorously analyzed using the WienerÀHopf technique for the E-polarized plane-wave incidence. Applying a method similar to that developed in Part I of this two-part article, exact and high-frequency asymptotic solutions are both obtained. Numerical examples of the far-field intensity are presented, and scattering characteristics of the waveguide slit are discussed. Some comparisons with our results for H polarization are also given.

The diffraction by a slit formed by two semi-infinite parallel-plate waveguides is rigorously analyzed using the WienerÀHopf technique for the H-polarized plane-wave incidence. 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 WienerÀHopf equations, which are solved via the factorization and decomposition procedure leading to exact and highfrequency asymptotic solutions. Taking the inverse Fourier transform and applying the saddle point method, the scattered field in real space is derived. Numerical examples of the far-field intensity are presented and scattering characteristics of the slit are discussed.
