"optical metamaterial's layers twist/ overlap changes how interacts with light (phase, polarization, wavelength)... single device outputs this detailed information, and clear images... MEMS technology controls gap/ angle between layers... compact, scalable, highly tunable flat-optics controls, suitable for versatile light manipulation and information processing tasks... layers sit on vertical/ rotary actuators, connected to electrode... quantum computing, data communications, satellites, medical scans"
