The Takeaway
Instead of needing a physical gadget to process signals, this framework uses clusters of surfaces to coordinate how electromagnetic waves move through the air. It essentially turns the volume of a room into a giant, invisible computer or antenna that manages information without a central hardware core.
From the abstract
The rapid evolution of next-generation communications and the Internet of Things (IoT) has catalyzed an urgent demand for governing expansive spatial environments as functional electromagnetic (EM) entities. However, deterministically programming such open EM spaces remains a formidable challenge, as current methodologies are largely confined to localized interfaces that lack the collective coordination required to orchestrate unbounded environments. Here, we introduce a general framework for th
