The article investigates graphene metasurface based infrared biosensor. Graphene metasurface perturbations are added in the Si3N4 waveguide to create leaky wave structure. Biomolecules in blood plasma form are placed over the Si3N4 waveguide to observe the sensing characteristics. Numerical results...
