This paper introduces a novel terahertz sensor leveraging spoof surface plasmon polaritons (SSPPs) for enhanced sensing capabilities. With the increasing demand for advanced sensing technologies, particularly in the terahertz range, there is a growing need for sensors that offer both sensitivity and versatility. The proposed sensor integrates a complementary split ring resonator (CSRR) structure with SSPP to achieve improved performance. Operating at a frequency of 1 THz, the sensor utilizes a SSPP-based transmission line with corrugated rectangular grooves, enabling tailored interactions with terahertz waves. This sensor design facilitates high sensitivity and specificity in material detection, making it suitable for various applications including biomedical diagnostics, security screening, and material analysis. By harnessing the unique properties of terahertz frequencies and controlled manipulation of surface plasmon polaritons, the sensor demonstrates promising prospects in diverse industries. © Anita Publications.
