Definition
The term, in context
AI-assisted draft · approved dataset
A Beyond-Diagonal RIS, or BD-RIS, is a reconfigurable intelligent surface whose internal scattering elements are interconnected rather than independently tunable, giving it a non-diagonal scattering matrix that can redirect and shape radio waves with more flexibility than conventional reconfigurable surfaces; a BD-RIS prototype is a physical hardware build used to test this wave-manipulation capability.
