EM scattering by an array of perfectly conducting strips by a physical optics approximation

Abstract: AbslrachThe scattering of electromagnetic waves by planar arrays of perfectly conducting strips is analymd by a simple method based on physical optics. The induced current as determined by physical optics is used in simple hand computation to obtain the amplitudes of various propagating space harmonics. Results are compared against some exact results available in the literature to show the accuracy of the proposed approximate method.

“…A number of methods have in the past been employed to solve problems of this type: point-matching (Ott et al 1967, Kalhor 1978, the Green's function method (Kalhor 1980), variational method (Meecham 1956, Primich 1957, Kalikstein and Sepulveda 1981 and integral-equation approximate solutions (Miles 1949), among others. The last two methods will be described and applied to strip gratings in later sections.…”

“…A Wiener-Hopf technique can be rigorously applied to the normally-incident plane-wave case [1,2]. This particular method has been cited many times, including several cases where it has been used for validation of methods applicable to less restricted geometries [3][4][5][6][7][8][9][10][11][12][13]. One reason for the popularity of the method is that it produces a simple and exact harmonic expansion with decoupled orders.…”
