Abstract:
1. A nuclear quadrupole resonance substance detection system comprising: at least one network analyzer having a frequency source to generate a signal in at least one discrete frequency, at least one power amplifier coupled with the at least one network analyzer to amplify the signal, at least one tuner coupled with the at least one power amplifier, at least one pair of monopole conductors coupled with the at least one tuner wherein the at least one pair of monopole conductors is driven by the at least one tuner and tuned to radiate the signal, at least one directional coupler coupled to the at least one tuner to detect stimulated emissions from a substance irradiated by the signal, a library of stimulated emission signatures for specific substances; and, a processor for correlating the detected stimulated emissions of the at least one directional coupler with the stimulated emission signatures in the library and for outputting a signal indicative of a match.
