Biomarker detection using GST-based permittivity-asymmetric metasurface
Abstract
Non-invasive detection of biomarkers can help in the early screening of lethal diseases, such as cancer and Alzheimer's. In this paper, we present a numerical study of a high-quality resonant permittivity-asymmetric metasurface that offers tunability in the mid-infrared range by employing the phase change property of Germanium Antimony Telluride, Ge3Sb2Te6 (GST326). In this approach, we used dissimilar materials of ellipse-shaped nanopillars, …
