N2 - Zinc Oxide (ZnO) has emerged as an intriguing material for environmental gas sensing. While many applications of ZnO thin films for gas sensing have been used, this paper proposes a novel technique in which ZnO thin films are patterned to form a lossy frequency selective surface (FSS). When the resistance of the ZnO changes with exposure to gas, there is a change in the amplitude and resonant frequency of the lossy FSS. A small change in the resonant frequency results in approximately 10 dB of amplitude shift at the original resonant frequency.
