Abstract

We analyze and discuss an ultra-compact metamaterial absorber (MA) by introducing meander lines into the resonant cells and covering another dielectric layer onto the MA. The size reduction procedures are presented step by step and an ultra-compact metamaterial absorber with in-plane (lateral) dimension of gamme/28 and vertical thickness of gamma/37 is obtained. We further present two variations of MA configurations which can reach similar ultra-compact sizes. The proposed ultra-compact MAs show near-unity absorption under a wide range of incident angles for both TE and TM radiations.
