dc.description.abstractThis paper presents a multi-faceted surface operating as a passive reflecting surface in a mm-wave scenario, typical for 5G/B5G or 6G communications. The reflecting surface has been optimized to adapt the orientation of the panels to an architectural element with an spherical profile (dome). The multi-faceted scheme consists of irregular triangular panels to ensure assembly and proper approximation of the doubly-curved spherical profile. Some preliminary electrical studies have been conducted to evaluate the reflecting electromagnetic skin. This structure demonstrates its feasibility to deviate the field to a certain direction of space, while it maintains a high camouflage with the environment.
