This paper investigates sidelobe level (SLL) optimization in multi-wavelength inter-element spaced sparse aperiodic arrays, a critical component of 6 G sparse transmitarray systems. A convex ...

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 ...
