Background:

Metasurfaces enable precise control of light reflection for applications like beam steering and imaging.
Achieving 100% anomalous reflection efficiency at optical frequencies remains a challenge due to losses and limited wave control.

Purpose of the Study:

To propose and demonstrate an all-dielectric metasurface structure for achieving perfect anomalous reflection at optical frequencies.
To overcome the limitations of existing metasurfaces in terms of reflection efficiency and nonlocal control.

Main Methods:

Design of a quasi-three-dimensional subwavelength structure using multilayer films and metagratings.
Stimulation of complex multiple scattering by coupling different Bloch and propagating waves.
Theoretical design and experimental validation of the metasurface performance.

Main Results:

Demonstrated two perfect anomalous reflectors for normally incident 1550-nm light.
Achieved high absolute efficiencies: 99% in design and 98%/88% in experiments for 40°/75° reflection directions.
Validated the metasystem's nonlocal control over light waves.

Conclusions:

The proposed all-dielectric metasurface structure enables highly efficient anomalous light reflection.
This work advances the development of high-efficiency optical metadevices for practical applications.
The findings pave the way for next-generation optical components with tailored light manipulation capabilities.
