(a) Shift in the center frequency for various conditions, (b) shift in the center frequency and variations in the reflection coefficient (S11) magnitude for water-glucose samples of varying concentrations from 0.25 to 5 mg/mL, (c) shift in the frequency and magnitude of the transmission coefficient (S21) at transmission zero, (d) linearly fitted center frequency (r2 = 0.9968), including the actual center frequencies with error bars, (e) shift in the center frequency and variations in the magnitude of the reflection coefficient (S11) for serum samples with glucose concentrations varying from 1.48 to 2.28 mg/mL and (f) linearly fitted center frequency (r2 = 0.9998), including the actual center frequencies with error bars.
