Abstract
The disclosure discloses a controllable wave-absorbing metamaterial including a substrate and a metamaterial unit array layer. Each conductive geometric unit includes a first hollow structure, second hollow structures, and conductive geometric structures. The second hollow structures are respectively extended from four vertices of the first hollow structure, and the conductive geometric structure is disposed between each two adjacent second hollow structures. The first end of the second hollow structure is provided with a varactor diode connected to the conductive geometric structures at both sides, the second end of the second hollow structure is provided with a fixed capacitor and a fixed resistor; the fixed capacitor is connected to the conductive geometric structure at one side, and the fixed resistor is connected to the conductive geometric structure at the other side. Therefore, active adjustment on a wave-absorption frequency band can be implemented, and power consumption is very low.
