Abstract

This paper presents a multi-layered, high-efficient metamaterial-based absorber operating at 3.7 GHz. The metamaterial is constructed on the basis of a single unit cell (UC) and possesses a compact board size of 25-by-25 sq. mm. It is imperative to mention that the UC parameters were optimized in order to obtain maximum efficiency. Besides, a feed line was added to the bottom layer that enables connecting the metamaterial to any given load with a 50-Ω impedance. Finally, the designed metamaterial demonstrated the double negative material properties and the absorbance efficiency of 85%.
