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 ...
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.
