MetaVenom: Field Programmable Fully Passive Metasurfaces

Emerging high frequency wireless sensing and communication systems often leverage metasurfaces to modulate the signal propagation, thereby transcending Snell's law. Yet, existing metasurfaces are either active, which is constantly sustained by electrical power, or passive, which cannot be reconfigured. In this paper, w...

FlowForm: Scalable Passive Metasurface Network for mmWave Coverage Expansion

FlowForm is introduced, a system that expands mmWave coverage using networks of passive metasurfaces that require no power, control, or runtime coordination, and develops a theoretical framework establishing the optimality of this topology and a hierarchical optimization algorithm that jointly determines metasurface pl...
