Scattering of H-Polarized Electromagnetic Wave by Infinite Dihedral Wedge Co-Axially Coupled with Slotted Cylinder

Abstract

Scattering of a plane Н-polarized electromagnetic wave by a perfectly conducting and infinitely extensive dihedral wedge, whose edge is placed on the axis of a circular cylinder with a longitudinal slot is in strict statement reduced to solving the system of linear algebraic equations of second kind with respect to the unknown coefficients of Fourier- expansions of the scattered field. It is shown that at the opening angle of a slot equal to the opening angle of a wedge, the solution is of analytical form. The calculation results for the field in the far zone are shown to the prescribed accuracy. It is also shown that for a narrow wedge and narrow slot for some values electrical diameters of a cylinder, the structure backscatter cross-section sharp increase takes place. The radiation patterns of a scattered field are constructed for different structure parameters.
