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.
