Title:
CONTROLLABLE WAVE-ABSORBING METAMATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/127938
Kind Code:
A1
Abstract:
A controllable wave-absorbing metamaterial, comprising: a substrate and a metamaterial unit array layer (2). The metamaterial unit array layer (2) is provided on the substrate; the metamaterial unit array layer (2) comprises multiple periodically arranged conductive geometry units, wherein each of the conductive geometry units comprises a first hollow structure (27), second hollow structures (28), and a conductive geometry structure (21); the second hollow structures (28) respectively extend from four vertices of the first hollow structure (27), and the conductive geometric structure (21) is provided between every two adjacent second hollow structures (28); each of the second hollow structures (28) comprises a first end facing toward the center of the conductive geometry unit and a second end facing away from the center of the conductive geometry unit; the first end of the second hollow structure (28) is provided with a variable capacitance diode (24) connected to the conductive geometric structures (21) at both sides, and the second end of the second hollow structure (28) is provided with a fixed capacitor (23) and a fixed resistor (22) spaced apart from each other; the fixed capacitor (23) is connected to the conductive geometric structure (21) at one side, and the fixed resistor (22) is connected to the conductive geometric structure (21) at the other side. The material can implement active adjustment of a wave-absorbing band, and the power consumption is extremely low.
