Regression Methods for Ophthalmic Glucose Sensing Using Metamaterials

Figure 3

S-matrix simulations of a simple dipole structure (a) and a coupled dipole and quadrupole antenna (c) with water and 20% glucose solution on top. A detailed view for smaller concentrations ranging from 1.25% down to 0.04% is given in (b) and (d), respectively. Figure (e) depicts the time averaged absolute values of the electric field in and around the structure at the resonance position.
