Backscatter reduction of long thin bodies by surface impedance modulation

We present a method for controlling the scattering of surface waves induced on long, thin, conductive bodies by grazing-angle illumination. We consider such bodies as travelling wave antennas and apply a modulated impedance coating to radiate the surface waves away from the illumination source, thus eliminating the large near nose-on monostatic scattering (backscatter). The effect on bistatic scattering is shown. We demonstrate the proposed concept with full-wave simulations.
