Terahertz frequency radiation possesses a unique combination of desirable properties for
noninvasive imaging and spectroscopy of materials. This includes the ability to obtain …

The detection of explosives and explosive related illicit materials is an important area for
preventing terrorist activities and for putting a check on their deleterious effects on health. A …

Spectroscopy in the terahertz frequency range has demonstrated unique identification of
both pure and military-grade explosives. There is significant potential for wide applications …

A novel method to prepare crack-free sol–gel materials without shrinkage is reviewed. The
method allows fabrication of a viscous sol–gel resin in a few minutes followed by either …

Publisher Summary This chapter describes detection of explosives by terahertz Imaging
(TM). There has been an amplified interest in terahertz (THz) detection for imaging of …

Terahertz time-domain spectroscopy in reflection mode geometry provides valuable surface
and subsurface information, making it suitable for a layer analysis, coating, and non …

The terahertz (THz), or far-infrared, region of the electromagnetic spectrum lies between the
mid-infrared and microwave/millimetre-wave regions. The THz range is conventionally …

We present a feasibility study to apply terahertz (THz) spectroscopy and THz imaging as non-
destructive diagnostic tools for sol–gel analysis, manufacturing and quality control. By …

Terahertz spectroscopy is a useful and an efficient method for detection of pure materials
and also mixture compounds. In the present study the terahertz spectra of the α-lactose, high …

Abstract Absorption spectra (0.2–1.8 THz) of the mixtures of explosive 2, 4-DNT and
polyethylene (PE) at different ratios are obtained using reflection terahertz time domain …
