Phys.org  August 30, 2023 To date research on metasurfaces has mainly focused on the full control of electromagnetic characteristics, including polarization, phase, amplitude, and even frequencies. Consequently, versatile possibilities of electromagnetic wave control have been achieved, yielding practical optical components such as metalenses, beam-steerers, metaholograms, and sensors. Researchers in South Korea focused on integrating the metasurfaces with other standard optical components for commercialization with miniaturization trends of optical devices. In this review they described and classified metasurface-integrated optical components, and subsequently discussed their promising applications with metasurface-integrated optical platforms including those of augmented/virtual reality, light detection and ranging, and sensors.
