Étude et conception d’un biocapteur métamatériaux à forte sensibilité

Abstract

In recent years, metamaterials have emerged as transformative materials that enable thedevelopment of innovative microwave components for a variety of applications. This the-sis presents the design, simulation, and implementation of a high-sensitivity microwavebiosensor utilizing metamaterial resonators. By harnessing the unique magnetic and elec-tric properties of metamaterials, this biosensor enhances detection capabilities, achievingremarkableaccuracyinidentifyingbiomoleculesattraceconcentrations.
