On the Universal Approximation Capability of Stacked Intelligent Metasurfaces
Davide Dardari
Wave-domain processing is an emerging paradigm in which signal-processing operations are partially shifted from the digital domain to the electromagnetic (EM) domain to reduce comp…
OAM-Enabled Holographic MIMO Communications with Stacked Intelligent Metasurfaces
Giulia Torcolacci, Davide Dardari
This study investigates orbital angular momentum (OAM)-based holographic multiple-input multiple-output (HMIMO) links enabled by stacked intelligent metasurfaces (SIM) in the radia…
Human-Inspired Pavlovian and Instrumental Learning for Autonomous Agent Navigation
Jingfeng Shan, Francesco Guidi, Mehrdad Saeidi +8
Autonomous agents operating in uncertain environments must balance fast responses with goal-directed planning. Classical MF RL often converges slowly and may induce unsafe explorat…
Near-Field Wideband Localization using TTD-Based Terahertz Extremely Large-Scale Arrays
Qianyu Yang, Haiyang Zhang, Francesco Guidi +4
The synergy between extremely large-scale antenna arrays and terahertz technology in sixth-generation networks establishes a near-field wideband transmission environment, enabling…
A Cognitive Framework for Autonomous Agents: Toward Human-Inspired Design
Francesco Guidi, Jingfeng Shan, Mehrdad Saeidi +8
This work introduces a human-inspired reinforcement learning (RL) architecture that integrates Pavlovian and instrumental processes to enhance decision-making in autonomous systems…
