High-sensitivity dual-band microwave CO₂ sensing using SWCNT/g-C₃N₄ nanocomposite-functionalized CSRR-loaded antennas

Carbon dioxide (CO₂) monitoring is essential for environmental protection, industrial process control, and indoor air-quality assessment, driving the development of compact, highly sensitive, and low-power sensing technologies. In this work, dual-band microwave CO₂ sensors based...
