Abstract :
A method for reducing the back scattering from bodies with complex impedance boundaries is developed. A nonlinear integral equation system providing zero backscattering is obtained for determining the impedance distribution on the boundaries of infinite cylinders. Numerical results for circular and elliptic cylinders are given. Frequency dependence of backscattering at obtained optimal impedance is discussed on the example of circular cylinder.
