Beam regulation structure and apparatus, and electronic device

A beam regulation apparatus, comprising:

• a plurality of beam regulation structures, wherein each of the beam regulation structures comprises:
• a waveguide layer and a grating layer disposed on the waveguide layer;
• wherein the grating layer comprises a plurality of functional structures and connection portions disposed between the plurality of functional structures, slit openings running through the functional structures along a thickness direction of the functional structure being formed in the functional structures;
• and
• the beam regulation structure further comprises a plurality of regulation units, wherein one of the regulation units is disposed on a side, away from the waveguide layer, of one of the functional structures, and each of the regulation units comprises a first regulation component and a second regulation component that are successively disposed along a direction away from the functional structures;
• wherein
• the first regulation component is configured to transmit or scatter an electromagnetic wave fed from the waveguide layer through the slit opening;
• and
• the second regulation component is configured to tune a phase of the electromagnetic wave transmitted by the first regulation component,
• wherein the first regulation component comprises a first electrode and a second electrode disposed opposite to each other, and a first tunable dielectric layer disposed between the first electrode and the second electrode, wherein the first tunable dielectric layer is configured to transmit or scatter, based on a voltage applied between the first electrode and the second electrode, the functional structure serves as the first electrode of the first regulation component disposed thereon.
