Application of THz spectroscopy for localisation of fibre optics embedded into glass fibre reinforced composite
Mieloszyk, Magdalena, Katarzyna Majewska, and Wieslaw Ostachowicz. "Application of THz spectroscopy for localisation of fibre optics embedded into glass fibre reinforced composite." Composite Structures (2018).
Recently, in many industrial branches (e.g. aviation, marine or civil engineering) metal elements are replacing by composite ones. To ensure their reliability structural health monitoring systems also based on fibre optics sensors (embedded into or mounted on composite structure) are widely applied.

… 2.1. THz unit. During the experimental investigation the THz spectrometer (TPS Spectra 3000 THz Pulsed Imaging and Spectroscopy from TeraView ® ), presented in Fig. 2, was used. The system contains two main parts: a measurement chamber and a scanning unit …
Polarizability of Aspirin at Terahertz Frequencies Using Terahertz Time Domain Spectroscopy (THz-TDS)
Zhang, Tianyao, Zhaohi Zhang, and Mark Arnold. "EXPRESS: Polarizability of Aspirin at Terahertz Frequencies Using Terahertz Time Domain Spectroscopy (THz-TDS)." Applied Spectroscopy (2018): 0003702818815177.
A novel application of terahertz time-domain spectroscopy (THz-TDS) is described for the determination of permittivity and polarizability of organic crystals, as exemplified by measurements with the polymorph I form of crystalline aspirin (acetylsalicylic acid). The coherent nature of the THz pulse experiment, coupled with gated-detection, permits direct measure of differences in the phase angle of the electric field vector after passing through a pellet composed of the aspirin crystals embedded within an inert polymer matrix. An effective …

Non-Destructive Fault Localization in Fan Out Wafer Level Packages Using Electro Optical Terahertz Pulse Reflectometry
Rho, Kyungsoo, Jongmin Lee, Daejin Kim, Thomas White, and Jesse Alton. "Non-Destructive Fault Localization in Fan Out Wafer Level Packages Using Electro Optical Terahertz Pulse Reflectometry." In 2018 IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits (IPFA), pp. 1-4. IEEE, 2018.
Here, we demonstrate how electro optical terahertz pulse refiectometry (EOTPR), a time-domain refiectometry technique that utilizes terahertz frequency electrical pulses to identify device faults, can be used to quickly and non-destructively isolate faults in advanced fan-out wafer level (FOWL) packages. We present a case study to show how EOTPR can accurately locate faults in the densely spaced redistribution layers (RDLs) of the package.
