Abstract :
In this paper, a novel wideband metamaterial (MM) absorber is proposed. The proposed absorber is composed of a hexagonal MM structure and a resistor-capacitor (RC) layer, with an air gap between the two layers. The additional RC layer comprises a series resistor and capacitor; this layer and an air gap have an important effect on the wider bandwidth. The proposed absorber shows absorbing properties over a very wide bandwidth. The performance of the proposed absorber is demonstrated by simulation and measurement results.
