Oct 24, 2018 · Here, we show that the metasurface nonlocality can be engineered to enable signal manipulation in the momentum domain over an ultrathin platform. We explore nonlocal metasurfaces performing basic mathematical operations, paving the way towards fast and power-efficient ultrathin devices for edge detection and optical image processing.

Dec 11, 2019 · Here, we introduce dielectric metasurfaces that perform optical image edge detection in the analog domain using a subwavelength geometry that can be readily integrated with detectors. The metasurface is composed of a suitably engineered array of nanobeams designed to perform either first- or second-order spatial differentiation.

Mar 28, 2024 · Now Hoyeong Kwon at the Center for Advanced Meta-Materials, South Korea, and Andrea Alù at the City University of New York have proposed a ring-shaped device that could noninvasively, directly measure blood-glucose levels with a …

Mar 28, 2024 · Our study opens a possible way of developing portable glucose monitoring systems that can detect the glucose concentration with a noninvasive approach and improved accuracy compared with existing techniques.
