Wiener-Hopf Analysis of the Plane Wave Diffraction by a Thin Material Strip: the Case of E Polarization

Plane-Wave Diffraction by a Slit in a Thin Material Screen

“…Applying the asymptotic method established in our previous work [1,2] to the branch-cut integrals in (31), we derive an explicit asymptotic solution to the Wiener-Hopf equation ( 20) with the result that…”

“…The unknowns f us;ud n in (33) are determined by following a procedure similar to that used in [1,2], but the details are omitted here. Equation ( 21) can be also solved in a similar manner.…”

“…A number of scientists have analyzed slit-diffraction problems using various analytical and numerical methods. In our pervious work [1,2], we have analyzed the plane-wave diffraction by a thin material strip using the Wiener-Hopf technique [3] and approximate boundary conditions [4], and obtained a rigorous, high-frequency solution. In this article, we shall consider a slit in an infinitely thin material screen and analyze the Hpolarized plane-wave diffraction with the aid of the Wiener-Hopf technique by following a procedure similar to that used in [1,2].…”
