About
K.A. Karthigeyan is a leading researcher in terahertz (THz) metamaterials and advanced electromagnetic sensors, with a focus on designing high-performance, polarization-dependent devices for sensing and detection. Their most notable contribution is the development of a dual-band, ultra-narrowband THz metamaterial sensor based on a novel "modified Trishul" structure, which achieves exceptional quality factors and figures of merit. This work, published in 2023 and garnering 32 citations, demonstrates a three-layer absorber design—gold metallic patches on a dielectric substrate above a conducting ground plane—enabling precise, polarization-sensitive sensing in the THz regime. Karthigeyan’s innovations push the boundaries of metamaterial sensor sensitivity, offering transformative potential for applications in biomedical diagnostics, security screening, and environmental monitoring. Their research stands out for its elegant combination of structural simplicity and record-breaking performance metrics, making it a benchmark for future THz sensor designs. With a growing citation impact, Karthigeyan is establishing themselves as a key contributor to the field of photonic and plasmonic metamaterials, inspiring new directions in ultra-sensitive, label-free detection technologies.
