摘要

我们展示了一种基于MEMS的可调谐滤波器,该滤波器具有太赫兹频率下可重构的电分裂环谐振器(eSRR)。这是通过制作具有应力弯曲梁(eSRR- scb)的eSRR平面阵列来实现的,eSRR- scb由静电力在平面外驱动。我们的研究结果表明,essr - scb在太赫兹频率下具有蓝移能力和偏振依赖状态,而这种自适应超材料在实现传感器、开关和滤波器等多种应用的新型电磁功能方面具有巨大的潜力。

A 3-D movable THz filter using surface micromachining process
We have demonstrated a MEMS based tunable filter with reconfigurable electric split-ring resonators (eSRR) at THz frequencies. This is accomplished by making planar arrays of eSRR with stress curved beams (eSRR-SCBs) which are actuated out-of-plane by electrostatic force. Our results have demonstrated that the eSRR-SCBs possess blue shifting capabilities and polarization dependent state at THz frequencies, while such adaptive metamaterials offer significant potential in realizing novel electromagnetic functionality with diversified applications such as sensors, switches, and filters.
