基于VO 2的温控可调谐极化无关超材料吸波体设计
Design of tunable polarization-unrelated metamaterials absorber based on VO2
摘要
Abstract
Based on the insulator-metal phase transition property of vanadium dioxide thin film (VO2), a thermally-control tunable polarization-unrelated metamaterials absorber was proposed and the microwave absorption and thermally tunable properties of one-ring, two-rings and three-rings structural metamaterials absorber were studied. The one-ring, two-rings and three-rings structural metamaterials absorber respectively appears one, two and three absorption peaks at the range of 2–20 GHz when the electromagnetic wave is vertically incident. The absorption peaks gradually increase with the increasing of ring. The absorption property is polarization-unrelated due to its two-dimensional omnidirectional symmetry. When the temperature changes from 40℃ to 80℃, the absorption properties have obvious change. It achieves the effect of polarization-unrelated tunable metamaterials absorber.关键词
