Experimental Verification of a Triple Band Thin Radar Absorber Metamaterial for Oblique Incidence Applications

This paper presents the theory, design, and experimental investigation of an ultra thin (6% ) and triple band metamaterial radar absorber. The theoretical design of the reported absorber is investigated. The absorber performance was validated using the electromagnetic simulations and confirmed by experimental measurements for different incidence angles. The results confirm that the proposed metamaterial absorber can demonstrate triple bands with better than -15 dB reflection coefficient for all incident angles.
