Abstract:

The theoretical study on the reduction of the backscattering of the infinite cone and the sphere by the impedance loading method is presented. An inifinite cone is assumed to be illuminated by a plane wave at the nose-on incidence. The backscattering of the cone is minimized by loading the cone surface with 1 a circumferential slot backed by an impedance, 2 a radial slot backed by an impedance and 3 a patch impedance. The sphere is given a similar treatment with the impedance area being in the shape of the wedge and the patch. For both the infinite cone and the sphere, it is shown that the optimum impedance for each case can be found to make the backscattering vanish. Author
