A review of gap-surface plasmon metasurfaces: fundamentals and applications (2018, methodology): “To perfectly control reflection, one may use properly engineered bi-anisotropic meta-atoms [55, 56] or strong nonlocal response [57].”
Intelligent Metasurfaces with Continuously Tunable Local Surface Impedance for Multiple Reconfigurable Functions (2018, background): “In fact, these parasitics can be suppressed by constructing appropriately designed supercells that promote reflection to a specific diffraction order while suppressing radiation to other diffraction orders [36, 39–43], realizing nearly perfect anomalous reflection.”
Prospective Multiple Antenna Technologies for Beyond 5G (2019, background): “Ideally, this should be done in a continuous way over the surface [161], but metasurfaces approximate this using many discrete “meta-atoms” of a sub-wavelength size that each induces a distinct phase-shift [162].”
Huygens’ metasurfaces from microwaves to optics: a review (2018, methodology): “[70], which showed good efficiency for two different cases of refraction (0° to −70° and 20° to −28°) at 10 GHz.”
Power Scaling Laws and Near-Field Behaviors of Massive MIMO and Intelligent Reflecting Surfaces (2020, background): “By controlling the phase-shifts of the individual elements, the metasurface can “reflect” an incident wave as a beam in the desired direction [14]; the physics is the same as for beamforming using a phased array, except that the array then generates the signal locally.”
