Conceptual illustration of the retro‐reflective and transmissive metasurface (RRTM). The blue radar establishes communication with the UAV via the transmissive mode, whereas the purple surveillance radar acquires the status of friendly units through the retro‐reflective mode and the two modes operate simultaneously within the same decoupled aperture ...
