In this article, we survey various non-contact, non-destructive testing methods by way of
terahertz (THz) spectroscopy and imaging designed for use in various industrial sectors. A …

The frequency range of terahertz waves (THz waves) is between 0.1 and 10 THz and they
have properties such as low energy, penetration, transients, and spectral fingerprints, which …

Broadband terahertz spectroscopy enables many promising applications in science and
industry alike. However, the complexity of existing terahertz systems has as yet prevented …

We carried out an experimental comparison study of the two most established optoelectronic
emitters for continuous-wave (cw) terahertz generation: a uni-traveling-carrier photodiode …

Terahertz (THz) technology has firmly established itself as an effective sensing and
nondestructive testing (NDT) technique for the detection of substances and physicochemical …

High-spectral-purity frequency-agile room-temperature sources in the terahertz spectrum are
foundational elements for imaging, sensing, metrology, and communications. Here we …

We present a design of electric split-ring resonators (eSRR) to explore its electromagnetic
coupling effect. eSRR is composed of metal-insulator-metal (MIM) configuration. The …

We present photomixers made of iron doped indium gallium arsenide (InGaAs: Fe) as
broadband receivers in optoelectronic continuous wave (cw) terahertz (THz) systems …

With the fast magnification of terahertz (THz) technology, it becomes necessary to regulate
the terahertz wave transmittance resourcefully. THz filters are crucial for managing devices …

We report rectification spectroscopy (RS) for single molecules performed with continuous-
wave terahertz (CW THz) radiation at the tunneling junction of a scanning tunneling …
