An ultrathin terahertz lens with axial long focal depth based on metasurfaces
TL;DR: Experimental measurements have demonstrated the designed ultrathin LFD THz lens's LFD property, which basically agree with the theoretical simulations and should have wide potential applications in broadband THz imaging and THz communication systems.

A broadband terahertz ultrathin multi-focus lens.
TL;DR: The proposed method produces an ultrathin, low-cost, and broadband multi-focus lens for THz-band application that demonstrates a good focusing function over a broad frequency range from 0.3 to 1.1 THz.
Wavelength de-multiplexing metasurface hologram.
TL;DR: A wavelength de-multiplexing metasurface hologram composed of subwavelength metallic antennas is designed and demonstrated experimentally in the terahertz (THz) regime, demonstrating a candidate way to design multi-colors optical display elements.
