Tunable Broadband Terahertz Metamaterial Absorber Based on Vanadium Dioxide and Graphene

We propose a dynamically tunable ultra-broadband terahertz metamaterial absorber, which was based on graphene and vanadium oxide (VO₂) and numerically demonstrated. The excellent absorption bandwidth almost entirely greater than 90% was as wide as 6.35 THz from 2.30 to 8.65 THz under norm...
