Independent Amplitude and Phase Modulation in Active Transmissive Metasurfaces via Complex Permittivity Tuning
Active metasurfaces are a promising platform for spatial light modulators (SLMs) in applications such as holography, beam shaping, and light detection and ranging (LiDAR), as they enable dynamic control over the amplitude and phase of light at subwavelength scales. Among these, transmissive metasurfaces offer a compact...
