1. A system for detecting an at least one condition of interest relating to a tube comprising:
- a split-ring resonator component configured to interface with the tube, wherein the split-ring resonator component comprises;
a transmitting antenna configured to transmit microwave energy;
a receiving antenna configured to receive the microwave energy; and
a split-ring resonator positioned between the transmitting and receiving antennas and positioned adjacent to the tube, wherein the split-ring resonator is adapted to vary at least one parameter of the microwave energy in response to an existence of the at least one condition of interest; and
a detection component operatively coupled to the split-ring resonator component, the detection component configured to detect the at least one condition of interest.

Abstract
A system, method, and apparatus for detecting at least one condition of interest relating to a tube, e.g. the presence of an air bubble. In some embodiments, the sensor includes antennas, a split-ring resonator, a frequency generator capable of generating frequencies in the microwave range, and a detection component. The detection component may estimate at least one parameter of received microwave energy in order to determine if a condition of interest exists.
