Diffraction of Em Plane Wave by a Slit in an Impedance Plane Using Maliuzhinets Function

Abstract

Abstract-Diffraction of an electromagnetic plane wave from a slit in an impedance plane has been presented. The method is based on Maliuzhinets technique for impedance surfaces. Comparison of the field patterns with different values of the face impedance are also presented.

Method of Additive Regularization of Field Integrals in the Problem of Electromagnetic Diffraction by a Slot in a Conducting Screen, Placed Before a Dielectric Layer

“…The above obtained formulas (8), (27), (45) provide calculation of the field in any point of space and represent the regularized solution of the problem of the plane electromagnetic wave diffraction by a perfectly conducting screen of arbitrary thickness with a slot and with a plane dielectric layer, placed behind it. As an illustration, we present results of computation of various spatial field components at wave diffraction for two polarizations, pictured in Fig.…”

“…The problem of plane wave diffraction by a slot in a perfectly conducting screen is one of the primary model problems of the electromagnetic waves propagation theory [1,2], because a slot can be considered as the simplest model of an aperture. That is why during a lot of years many authors have solved this problem using various methods (see, for example, [3][4][5][6][7][8][9][10]). A rigorous approach to solving such problems is provided by the eigen-modes technique [11], which is successfully applied to simulation of fields in diffraction, waveguide, and resonator structures of various geometries (see, for example, [12][13][14][15]).…”

Diffraction Field Behavior Near the Edges of a Slot and Strip

“…There are a lot of works, where such diffraction problems are studied under various boundary conditions exactly and approximately (see, for example, [9][10][11][12][13]). However, as it is known for us, only in the work of [8] their exact solutions under the classical formulation of boundary conditions are presented for the first time.…”

Diffraction of Plane Wave by Strip With Arbitrary Orientation of Wave Vector

“…For small angle values, a K-H approximation gives poor results. Other methods as Kobayashi potential method [7], Maliuzhinet's techniques [8] could be used to solve the problem. The best result was achieved by Ufimtsev [9] who obtained the solution for a strip in the form of a series in sequential edge waves excited by different its edges.…”
