Plug-In RIS: A Novel Approach to Fully Passive Reconfigurable Intelligent Surfaces
Mahmoud Raeisi, Ibrahim Yildirim, Mehmet Cagri Ilter +2
This paper presents a promising design concept for reconfigurable intelligent surfaces (RISs), named plug-in RIS, wherein the RIS is plugged into an appropriate position in the env…
Reconfigurable Intelligent Surface Deployments for Mars: Communication and Localization Across Diverse Terrains
Enes Koktas, Recep A. Tasci, Ibrahim Yildirim +1
Space exploration has witnessed a steady increase since the 1960s, with Mars playing a significant role in our quest for further knowledge. As the ambition to colonize Mars becomes…
Practical Implementation of RIS-Aided Spectrum Sensing: A Deep Learning-Based Solution
Sefa Kayraklik, Ibrahim Yildirim, Ertugrul Basar +2
This paper presents reconfigurable intelligent surface (RIS)-aided deep learning (DL)-based spectrum sensing for next-generation cognitive radios. To that end, the secondary user (…
Antenna Array Structures for Enhanced Cluster Index Modulation
