Wideband All-Dielectric Reflector at 100 GHz for 6G Communications

Power-efficient systems are required for 6G communications. Part of a window real-state can be used as placement of a reflecting metasurface, which can provide coverage to users in scenarios, where there are no line-of-sight links. In this contribution, we propose a wideband all-dielectric metasurface at 100 GHz that consists of alumina posts on plastic and does not depend on the angle of incidence. The design has been manufactured and measured, with good agreement between measurements and simulations.
