This paper demonstrates the feasibility of reducingradar cross-section by employing resistive sheets or rings inthe conducting elements of an FSS unit cell. The idea behindthe approach in question is to create power-absorbing elementswhich may help reduce the power reflected from FSS surface.The investigated FSS unit cells have the form of double-closedrings and double-closed-split rings. A carbon paste, serving asthe resistive layer, was inserted in various regions within the unitcell. The CST Microwave Studio software was used to obtain thereflection coefficient. Specific dimensions and conductivity of thepaste were selected to ensure better performance. Simulationresults showed that the reflection coefficient may be reduced by 8 dB, to14d B, by using carbon paste with the conventionalcopper layer.
