WebThe main difficulty in solving matrix Wiener–Hopf equation arises from the fact that there are coupled scalar equations. In some situations the coupling is small and a reasonable … Webthat Hopf’s name was dropped from the discrete version of the Wiener-Hopf equation, which is now referred to as the ‘Wiener fllter’. During the 1940s it was discovered that problems involving difiraction by semi-inflnite planes/geometries could, by using Green’s theorem, be formu-lated in terms of integral equations of the form of (1).
WebIn this work, we introduce a general method to deduce spectral functional equations and, thus, the generalized Wiener–Hopf equations (GWHEs) for wave motion in angular regions filled by arbitrary linear homogeneous media and illuminated by sources localized at infinity with application to electromagnetics.
