Executive Summary A team of researchers from KTH Royal Institute of Technology, INSA Rennes, the University of Bordeaux, and ESA has developed and experimentally validated a fully metallic geodesic Luneburg lens antenna that operates in the sub‑terahertz (sub‑THz) frequency band between 128 and 132…

Pushing Sub-THz Frontiers: Our Fully-Metallic Geodesic Luneburg Lens Antenna Why Sub-THz Luneberg lens Matters Classical Luneburg lenses have too much losses above 80 GHz. Together and colleagues at KTH Stockholm, ESA Noordwijk and IETR Rennes, we decided to tackle those issues head-on with a radically different solution—one that would rely on purely metallic wave-guiding optics … Read more
