Reconfigurable Intelligent Surfaces (RISs) have emerged as an essential technology for the next generation of wireless communication systems. They have the potential of improving …
Misfocus or beam squint, is a fundamental prob-lem for reconfigurable intelligent surface (RIS)-assisted beam-forming. In this work, we investigate two methods for misfocus …

In this contribution, we propose, design, simulate and prototypically realize a 3-bit digital coding metasurface by controlling the phase and amplitude response of the metasurface …
Distinguishing between reconfigurable intelligent surface (RIS) assisted paths and non-line- of-sight (NLOS) paths is a fundamental problem for RIS-assisted integrated sensing and …
