Method and apparatus for sensing the presence of explosives, contraband and other molecules using nuclear quadrupole resonance and a swept frequency continuous wave source

摘要

Stimulated emissions due to nuclear quadropole resonance are detected utilizing a terminated balanced transmission line and a directional coupler for the detection of explosives, contraband, narcotics and the like that exist between the transmission lines, in which a swept frequency continuous wave generator is utilized to scan between 100 KHz and 10 MHz.
