Abstract The terahertz (0.1–10 THz) range represents a fast-evolving research and industrial
field. The great interest for this portion of the electromagnetic spectrum, which lies between …

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 …

In this work, we improve the performance of an optically pumped spintronic terahertz emitter
(STE) by a factor of up to 6 in field amplitude through an optimized photonic and thermal …

Spintronic terahertz emitters are broadband and efficient sources of terahertz radiation,
which emerged at the intersection of ultrafast spintronics and terahertz photonics. They are …

This new edition of Infrared and Terahertz Detectors provides a comprehensive overview of
infrared and terahertz detector technology, from fundamental science to materials and …

The phenomena and recent progress in the evolution of the basic classes of the THz
detectors that exist today are considered. Issues associated with the development and …

The gyrotrons are powerful sources of coherent radiation that can operate in both pulsed
and CW (continuous wave) regimes. Their recent advancement toward higher frequencies …

Terahertz (THz) spectroscopy systems are widely employed to retrieve the chemical and
material composition of a sample. This is single-handedly the most important driving …

Terahertz (THz) oscillators based on resonant tunneling diodes (RTDs) have relatively low
output power, tens to hundreds of microwatts. The conventional designs employ submicron …

The use of massive multiple-input multiple-output (MIMO) systems is becoming
progressively feasible, as well as progressively important, as the carrier frequency …
