Experimental study of the electrodynamic properties of an open cylinder in a rectangular waveguide
Abstract
Experimental results are presented on H(10)wave scattering by an open hollow cylinder with a longitudinal slot at a frequency of 10 GHz; the cylinder was situated so as to be parallel to the wide wall of a rectangular waveguide with a cross section of 23 x 10 mm. The study was undertaken in order to determine the limits of applicability of results of the rigorous solution of diffraction problems conditioned by the finite conductivity and thickness of the walls of curved open screens. It is shown that the modeling of slotted cylindrical structures as infinitely thin curved screens makes possible a good description of such structures if the wall thickness is of the order of 0.01 lambda sub g (where sub g is wavelength in the guide). The main discrepancy between experimental and theoretical data for thin cylinders is due to the effect of the finite conductivity of the walls.
