About

E. Papanasam is a leading researcher in the field of terahertz (THz) metamaterials, with a specific focus on high-performance sensors and absorbers. Their work is centered on designing ultra-narrowband, polarization-dependent structures that achieve exceptional quality factors (Q) and figures of merit (FOM). A key contribution is the development of a dual-band THz metamaterial sensor based on a modified "Trishul" structure, a three-layer design comprising a gold ground plane, a dielectric substrate, and a patterned metallic patch. This innovation enables precise, polarization-sensitive detection, making it highly valuable for advanced sensing applications in spectroscopy and imaging. With their most-cited paper accumulating 32 citations since 2023, Papanasam’s research demonstrates significant impact in the rapidly evolving area of metamaterial engineering. Their work not only pushes the boundaries of THz device performance but also offers practical pathways for creating compact, high-efficiency sensors, establishing them as a notable contributor to next-generation photonic technologies.
