摘要

随着太赫兹超材料吸收器的快速发展，可调谐器件成为实现电磁调制的关键。本研究利用二氧化钒（VO2）的金属-绝缘体转变（MIT），提出了一种具有可切换带宽的相变驱动的超材料吸收体。其三层结构包括金（Au）底平面、聚四氟乙烯（PTFE）间隔层和vo2金（Au）谐振器阵列。模拟显示了两种模式：金属VO2实现了超宽带吸收（2.97-7.12 THz, > 90%）；绝缘VO2在9.43 THz （>； 99%吸光度）处表现出窄带共振，质量因子为204.1，灵敏度为1018 GHz/RIU。在50°入射下，它的吸收率为90%，对偏振不敏感。这种双功能设计通过可调带宽打破了传统隐身材料的限制，集成了隐身和传感，并为军事伪装、环境监测和生物医学领域的自适应太赫兹系统提供了新的可能性。

Tunable wide- and narrow-band terahertz metamaterial absorber using vanadium dioxide

With the rapid development of terahertz metamaterial absorbers, tunable devices are critical for electromagnetic modulation. This study proposes a phase-transition-driven metamaterial absorber with switchable bandwidth, utilizing vanadium dioxide (VO₂)'s metal-insulator transition (MIT). Its tri-layer structure includes a gold (Au) bottom plane, polytetrafluoroethylene (PTFE) spacer, and VO₂-gold (Au) resonator array. Simulations show two modes: metallic VO₂ enables ultra-broadband absorption (2.97–7.12 THz, >90 %); insulating VO₂ exhibits narrowband resonance at 9.43 THz (>99 % absorbance) with quality factor 204.1 and sensitivity 1018 GHz/RIU. It operates polarization-insensitively with >90 % absorption at 50° incidence. This dual-functional design breaks traditional stealth material limitations via adjustable bandwidth, integrates stealth and sensing, and offers new possibilities for adaptive terahertz systems in military camouflage, environmental monitoring, and biomedical fields.
