Abstract: Reducing the number of antenna elements within a fixed aperture while maintaining low sidelobe levels is a key challenge in sparse array design. Although various sidelobe suppression ...
A new roll-based printing method could help turn fragile nanowire forests into dense, aligned, flexible electronic layers for wearable sensors, UV photodetectors, and next-generation device platforms.
Abstract: This work presents a metagrating (MG)-assisted sparse array based on a unified analytical and practical design framework. A Floquet-Bloch (F-B) modal approach is developed with practical ...
