Abstract
A system for forming a beam includes one or more wave sources; one or more surface scattering antennas (for example, one or more holographic metasurface antennas) coupled to the one or more wave sources, wherein each of the one or more surface scattering antennas comprises an array of scattering elements that are dynamically adjustable in response to one or more waves provided by the one or more wave sources to produce a beam; and a beam shaper configured to receive the beam from each of the one or more surface scattering antennas and to redirect the beam, preferably, with gain.

A system for forming a beam, comprising:
- one or more holographic metasurface antennas (HMAs) that include an array of scattering elements that produce one or more beams based on one or more wave signals;
- and
- a shaper that passively redirects the one or more beams, wherein a physical arrangement of the shaper provides an aperture that is relatively larger than another aperture provided by the one or more HMAs.
A shaper for directing one or more beams, comprising:
- a surface that receives the one or more beams produced by an array of scattering elements for one or more holographic metasurface antennas (HMAs) based on one or more wave signals, wherein the surface passively redirects the one or more beams;
- and
- wherein a physical arrangement of the surface provides an aperture that is relatively larger than another aperture provided by the one or more HMAs.
A holographic metasurface antennas (HMAs) for forming one or more beams, comprising:
- an array of scattering elements that produce the one or more beams based on one or more wave signals;
- and
- wherein the HMA provides the one or more beams to a shaper that passively redirects the one or more beams, wherein a physical arrangement of the shaper provides an aperture that is relatively larger than another aperture provided by the one or more HMAs.
