To give you a glimpse of the research work, here is a quote from the abstract: By proposing a fully resonant structure and introducing a mode-alignment technology, we report an isotropic angle-insensitive programmable metasurface (PMS) whose phase response is stable with respect to different incident angles in both elevation- and azimuth-planes. A radar scheme that uses such a PMS as a periscope is also demonstrated to detect drones in a non-line-of-sight (N-LOS) scenario which usually happens in an urban environment. Our proposed scheme enables those targets even falling in shadow areas caused by high buildings to be successfully detected and tracked, which shows promising potentials in N-LOS target detections.
