1. A system for performing a rapid antimicrobial susceptibility test, comprising:
a well including a cavity for receiving a sample containing a microbial population and an antimicrobial;
a sensor having a set of defined parameters positioned vertically in the well so that the sensor will contact the sample;
a receiver positioned under the well and wirelessly coupled to the sensor; and
an impedance analyzer connected to the receiver and configured to identify a resonance frequency of the sensor and the receiver, to record the resonance frequency over a predetermined set of first time periods, to calculate the permittivity of the sample based on the resonance frequency and the defined parameters of the sensor, and to track the permittivity over a second predetermined time period.
