设计并实现了一种包覆纳米结构碳纳米管（CNT）的超材料启发平面共振结构，用于检测丙酮和甲苯等有害气体的存在。一种由中心蚀刻圆槽和非对称地蚀刻圆互补裂环谐振器组成的改进设计拓扑结构。所设计的传感器对甲苯、丙酮等有害人体健康的气体具有较高的灵敏度。在室温（25℃）、相对湿度为32%的条件下，采用可控实验气敏装置对任意气体浓度进行实时监测。测量的传感性能表明，CNT- MCSRR传感器能够检测环境中存在的有害气体，因为它对丙酮和甲苯分别表现出370 MHz @ 350 ppm和170 MHz @ 300 ppm的大S21频移。
The design and implementation of Metamaterial inspired planar resonant structure coated with the nanostructured carbon nanotube (CNT) is carried out to detect the presence of hazardous gases viz., acetone, and toluene. A modified design topology consisting of center etched circular slot along with the asymmetrically ground etched circular complementary split ring resonator (CSRR). The designed sensor is found to be quite sensitive toward the human health-hazardous gases, including toluene and acetone gases. A controlled experimental gas sensing setup is used to perform the real-time monitoring of an arbitrary gas concentration at room temperature (25 0C) with RH 32%. The measured sensing performances revealed that CNT--MCSRR sensor is capable to detect hazardous gases present in the environment as it exhibited large S21 frequency shift of 370 MHz @ 350 ppm and 170 MHz @ 300 ppm for acetone and toluene, respectively.
