Journal ArticleDOI
Generation of arbitrary order Bessel beams via 3D printed axicons at the terahertz frequency range.
TL;DR: This 3D-printing-based Bessel beam generation technique is useful not only for THz imaging systems with zero-order Bessel beams but also for future orbital-angular-momentum-based THz free-space communication with higher-orderBessel beams.
Journal ArticleDOI
Ultrathin flexible terahertz polarization converter based on metasurfaces
TL;DR: A method to design and fabricate a kind of converters based on flexible metasurfaces which can change the polarization state of an incident terahertz beam by slightly changing the structure of the converter is presented.
Journal ArticleDOI
Terahertz image super-resolution based on a deep convolutional neural network
TL;DR: Experimental results on real THz images show that the proposed method significantly improves the quality ofTHz images with increased resolution and decreased noise, which proves the practicability and exactitude of the proposedmethod.
Journal ArticleDOI
3D-printed diffractive elements induced accelerating terahertz Airy beam
TL;DR: The propagation dynamics of the accelerating terahertz Airy beam is demonstrated and its self-healing property during propagation in the free space is investigated to develop novel THz imaging systems and robust THz communication links.
Journal ArticleDOI
Terahertz circular Airy vortex beams.
TL;DR: The THz circular Airy vortex beams (CAVBs) with a 0.3-THz continuous wave through 3D printing technology are demonstrated and the propagation dynamics of the generated THz CAVBs agree well with the observations.
