  • At terahertz frequencies, link discovery by scanning is impractically slow. Here, the authors propose an alternative, single-shot link-finding method based on a leaky-wave device.

  • Fresh produce can be wasted at many stages of the food supply chain. A metamaterial sticker is developed based on sub-terahertz signals to detect fruit ripeness, which can be used to optimize distribution and for waste prevention.

  • This study presents the first sub-THz retrodirective wideband backscatter. Instead of phased arrays, it uses key properties of leaky waveguides, i.e., frequency-angle dependency and reciprocity for wideband retro directivity with ultra-low power.
