| description | Edge scattering is one of the main scattering sources for metal objects, especially for those with thin front edges. In this paper, based on the principle of scattering cancelation, a coding metasurface purfle is proposed and employed to suppress the edge back-scattering of electromagnetic (EM) waves. To this end, two split-ring resonators with a π phase difference between them are designed to act as the 0- and 1-element of the coding metasurface. The coding metasurface fixed on the front edge of a thin metal plate can reduce the edge back-scattering significant for EM waves polarized along the edge direction due to the anti-phase scattering of the two coding elements. Both the simulation and experiment results verify the reduced back-scattering of the flat edge. A maximal reduction of 24 dB is attained within the central frequency of about 11 GHz. This work provides a novel alternative to suppressing edge scattering and may find applications in EM compatibility, radar stealth technologies, etc. |
