Title
(EN) Shipping container explosives and contraband detection system using nuclear quadrupole resonance
Abstract
(EN)

For container-carried explosives or contraband in which the container is made of conductive material and can therefore constitute a Faraday cage, stimulated emissions due to nuclear quadrupole 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 in metal containers.
