Wiener-Hopf technique

Wiener-Hopf technique

[¦vēn·ər ′hȯpf ‚tek‚nēk]
(mathematics)
A method used in solving certain integral equations, boundary-value problems, and other problems, which involves writing a function that is holomorphic in a vertical strip of the complex z plane as the product of two functions, one of which is holomorphic both in the strip and everywhere to the right of the strip, while the other is holomorphic in the strip and everywhere to the left of the strip.

The Wiener-Hopf technique [13-16] is known as a powerful approach for analyzing electromagnetic wave problems associated with canonical geometries rigorously, and can be applied efficiently to problems of the diffraction by specific periodic structures such as gratings.
As an example of infinite periodic structures with non-plane boundaries, Das Gupta [28] analyzed the plane wave diffraction by a half-plane with sinusoidal corrugation by means of the Wiener-Hopf technique together with the perturbation method.
As mentioned earlier, we have already analyzed the diffraction problem involving the same grating geometry for the E-polarized plane wave incidence using the Wiener-Hopf technique together with the perturbation method [32,33].
In this paper, we have analyzed the diffraction by a finite sinusoidal grating for the H-polarized plane wave incidence using the Wiener-Hopf technique combined with the perturbation method.
It contains all the significant topics of EM wave technology, from the finite element method, boundary element method, point-matching method, mode matching method, the spatial network method, the equivalent source method, the geometrical theory of diffraction, the Wiener-Hopf technique, asymptotic expansion techniques and beam propagation method to spectral domain method.
We'll use methods of the theory of singular integral equations [2,3,5,7], boundary value problems [1], and the Wiener-Hopf technique [8].
Further we'll apply the Wiener-Hopf technique to the equation (2.6) and write it in a convenient form:
