Terahertz science and technology promise many cutting-edge applications. Terahertz
surface plasmonic waves that propagate at metal–dielectric interfaces deliver a potentially …

Terahertz (THz) imaging can see through otherwise opaque materials. However, because of
the long wavelengths of THz radiation (λ= 400 μm at 0.75 THz), far-field THz imaging …

Terahertz (THz) near-field imaging is a flourishing discipline 1, 2, with applications from
fundamental studies of beam propagation 3 to the characterization of metamaterials 4, 5 and …

Terahertz and millimeter waves penetrate various dielectric materials, including plastics,
ceramics, crystals, and concrete, allowing terahertz transmission and reflection images to be …

Based on the complementary V-shaped antenna structure, ultrathin vortex phase plates are
designed to achieve the terahertz (THz) optical vortices with different topological charges …

In this work we report two designs of subwavelength fibers packaged for practical terahertz
wave guiding. We describe fabrication, modeling and characterization of microstructured …

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

Abstract Terahertz (THz= 1012 Hz) spectroscopy has been recognized as a promising
analytical technique for non-destructive, highly accurate investigation. However, despite its …

The interaction of high-power lasers with matter can generate Terahertz radiations that
efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in …

Using conventional materials, the resolution of focusing and imaging devices is limited by
diffraction to about half the wavelength of light, as high spatial frequencies do not propagate …
