Abstract
A method for analyzing a sample includes providing a sensor assembly having a sensing region with a plurality of resonant circuits, and a plurality of tuning elements. The method further includes exposing the sensor assembly to an environment comprising the sample, and probing the sample with one or more frequencies generated by the sensor assembly. Furthermore, the method includes determining an impedance of a sensor response over a measured spectral frequency range of the sensor assembly, and relating measurement of impedance of the sensor assembly to at least one environmental property of the sample.
