NMR & MW techniques for detection of explosive and illicit materials

Abstract

The detection of explosives and illicit substances is a very important problem nowadays. Especially, improvised explosive devices (IEDs) manufactured from homemade explosive materials has become an issue of growing importance. In this work, recent developments in the field of time domain (TD) NMR and microwave/sub-THz detection of liquid substances are reviewed. It has been shown that both TD NMR and MW dielectric spectroscopy are potentially very effective techniques to detect content of concealed liquids.
