Terahertz near-field microscopy based on an air-plasma dynamic aperture
TL;DR: In this article , an air-plasma dynamic aperture was developed for near-field imaging of four different materials, including metallic, semiconductor, plastic, and greasy samples, where two mutually perpendicular airplasmas overlapped to form a cross-filament above a sample surface that modulated an incident THz beam.
Thermally tunable THz filter made of semiconductors
TL;DR: In this article, the transmission properties of terahertz wave passing through two different periodic subwavelength structures on InSb semiconductor slabs under different temperatures have been investigated.

Generation of terahertz vector beams with a concentric ring metal grating and photo-generated carriers
TL;DR: Experimental results correspond to the theoretical simulations well and the proposed method is applicative for a broadband THz radiation and could be applied in the THz sensing, THz imaging, and THz communication in the future.

Continuous-wave terahertz interferometry with multiwavelength phase unwrapping.
Xinke Wang,Lei Hou,Yan Zhang +2 more
TL;DR: A multiwavelength phase unwrapping method is introduced to the cw THz phase imaging to reconstruct the exact phase map of the object and has the potential to improve the applications of cw Thz imaging.
