摘要

我们提出了一种新型的电可伸缩、可重构的频率选择表面(FSS)远红外滤波器，它是在透明、柔性聚酰亚胺衬底上制造的。我们提出的可重构性方法是通过采用相变材料(PCMs)实现的。本提案中主要考虑的PCM是二氧化钒(VO2)，因为它具有相对低温的可逆金属到绝缘体的转变，并且符合常见的制造技术。本文提出的可重构滤波器覆盖15 ~ 17 μm，阻带中心波长可在15.5 ~ 16.1 μm之间随VO2的活化而切换。虽然所提供的设计是针对远红外的，但它可以很容易地缩放以满足更长的波长和更低频率应用的需求。

Reconfigurable Far-Infrared FSS Filters on Polyimide Substrate

We present a novel electrically scalable, reconfigurable frequency selective surface (FSS) far-IR filter fabricated on transparent, and flexible polyimide substrate. Our proposed method of reconfigurabilty is achieved by employing phase change materials (PCMs). The PCM primarily considered in this proposal is vanadium dioxide (VO₂) due to its relatively low temperature reversible metal to insulator transition and conformity to common fabrication techniques. Here, the proposed reconfigurable filter covers 15–17 μm with a stopband center wavelength that can switch between 15.5 and 16.1 μm with the activation of VO₂. Although the design provided is intended for the far-infrared, it can easily be scaled to meet the needs of longer wavelength and lower frequency applications.

期刊介绍： The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
