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.

We are providing an unedited version of this manuscript to give early access to its findings. Before final publication, the manuscript will undergo further editing. Please note there may be errors ...

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 ...
