Terahertz (THz) frequency range, lying between the optical and microwave frequency
ranges covers a significant portion of the electro-magnetic spectrum. Though its initial usage …

In the last decades, many research teams working at Terahertz frequencies focused their
efforts on surpassing the diffraction limit. Numerous techniques have been investigated …

The photo-Dember effect is a source of pulsed THz emission following femtosecond pulsed
optical excitation. The emission results from the ultrafast spatial separation of electron–hole …

Heavy metal pollution of agricultural and urban soils limits economic progress in the rapidly
developing society. Terahertz technology is applied to detect heavy metal pollutants under …

Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency
bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost …

We observe intense pulses of far-infrared electromagnetic radiation emitted from arrays of
InAs nanowires. The terahertz radiation power efficiency of these structures is∼ 15 times …

Coaxial waveguides exhibit no dispersion and therefore can serve as an ideal channel for
transmission of broadband THz pulses. Implementation of THz coaxial waveguide systems …

We derive the spectral analogues of the Maxwell equations for describing the propagation of
electromagnetic waves in linear and weakly nonlinear dielectric media, which can be useful …

To clarify the ultrafast temporal interplay of the different photocurrent mechanisms occurring
in single InAs‐nanowire‐based circuits, an on‐chip photocurrent pump‐probe spectroscopy …

The region of the electromagnetic spectrum from 0.3 to 20 THz (10–600 cm-1, 1 mm–15 μm
wavelength) is an area for research that encompasses physics, chemistry, biology, materials …
