Low-index-metamaterial for gain enhancement of planar terahertz antenna

AIP Advances, 2014
We theoretically present a high gain planar antenna at terahertz (THz) frequencies by combing a conventional log-periodic antenna (LPA) with a low-index-metamaterial (LIM, |n| < 1).

Learning to See Around Corners: A Deep Unfolding Framework for Terahertz Radar Non-Line-of-Sight 3D Imaging

Photonics
Non-Line-Of-Sight (NLOS) Terahertz (THz) radar 3D imaging leverages electromagnetic wave propagation characteristics such as reflection, diffraction, scattering, and penetration to detect, locate, and image hidden targets in occluded environments.
