In this paper, we review the existing approaches for vortex and vector beam shaping and
generation in the terahertz frequency range. The particular focus of this review is on the …

Terahertz (THz) electromagnetic waves offer a new way of understanding various
phenomena, owing to their non-ionizing properties resulting from their low energy, and non …

Featured Application Non-destructive porosity measurements of 3D printed materials by
terahertz time-domain spectroscopy. Abstract The porosity and inhomogeneity of 3D printed …

The use of cyclic olefin copolymer (COC) as a material for material extrusion 3D-printing is a
novel approach in additive manufacturing. Its chemical inertness and high biocompatibility …

We present the design, fabrication, and experimental test of a THz all-dielectric phase shifter
plate. The design consists of two wave plate zones coupled in a perpendicular orientation …

We report the design, fabrication and experimental validation of a THz all-dielectric multi-
mode q-plate having a fixed rate of change of the optical axis. The device consists of space …

A fused deposition modeling (FDM) 3D printer extruder was utilized as a micro-furnace draw
tower for the direct fabrication of low-cost optical fibers. An air-clad multimode microfiber was …

Polarized THz time domain spectroscopy was used to study the anisotropic properties of
wood-based materials for potential optical elements in the THz range, such as half-wave …

Here we propose a 3D printed form-birefringent achromatic quarter-waveplate targeting the
lower terahertz frequency range. The monolithically fabricated waveplate consists of three …

Terahertz (THz) technology has been developed to meet advancements in spatial light
modulation of frequencies in the THz regime, where fast modulation techniques designed for …
