Abstract

In this paper, a relatively very simple structure for an X-band metasurface absorber is designed, along with its analysis. This structure is made with 0.35-mm-thick copper cladding over an abundantly available substrate FR-4 substrate having 3.1 mm thickness. This wideband metasurface absorber also exhibits more than 90% absorption throughout the frequency range of 6.58–14.44 GHz, with a fractional bandwidth of 74.45%. Hence, the designed MS absorber is applicable to the stealth, EMI reduction, and microwave energy harvesting applications.
