RESONANCE-FREQUENCY DIVERSE METAMATERIALS AND METASURFACES

摘要

A beamforming system, comprising a plurality of subsets of tunable resonator elements arranged on a substrate. Each subset of tunable resonator elements comprises at least two resonator elements that have a common resonance property modifiable by a common physical stimulus. A first control input may provide a first physical stimulus to modify the resonance property of all the tunable resonator elements in a first subset of tunable resonator elements. A second control input may provide a second physical stimulus to modify the resonance property of all the tunable resonator elements in a second subset of tunable resonator elements. A controller adjusts the first and second physical stimulus provided via the control inputs between a plurality of physical stimulus values. Each different physical stimulus value corresponds to one of a plurality of a unique resonance patterns and associated unique radiation patterns.
