Researching　and　developing　of　ultra-wideband　capability　and　high　light　transmittance　have　been　hot　issues　in　the　field　of　new　artificial　electromagnetic　stealth　material.　In　this　paper,　a　novel　transparent　metamaterial　absorber,　made　of　resistive　films　and　glass,　has　been　presented.　The　simulation　results　show　that,　under　the　incidence　of　plane　wave,　the　absorber　realizes　high　absorption　during　frequency　range　from　3.5　GHz　to　18.5　GHz　while　keeping　insensitive　to　polarization.　A　prototype　has　been　fabricated　and　tested,　and　the　measurement　results　are　in　good　consistent　with　simulation.　Along　with　its　high　transmittance　and　superior　absorption,　we　expect　that　the　absorber　has　great　potential　applications　in　RCS　(Radar　Cross　Section)　reduction　and　electromagnetic　shielding.
