摘要：Currently, implementation of active circuit elements withinmetamaterials is an effective
way to make them electrically tunable. We combine varactors with split copperloops in a metamaterial absorber in order to obtain electrically tunablemicrowave response. This absorber has a compact planar structure and asimplified back feeding network. Flexible frequency tunability of the microwavereflection in the range of 5~6 GHz is experimentally achieved. The design,simulation, and experimental results are systematically presented. The proposedmethod is scalable for developing active metamaterial absorbers based on metalloops, and demonstrates promising potential of active metamaterial absorbersfor extensive microwave applications.
