This paper presents the design of a sparse antenna array integrated with a metagrating for wide-angle beam scanning without grating lobes. The proposed design features a supercell configuration ...

In vision-language models (VLMs), visual tokens usually consume a significant amount of computational overhead, despite their sparser information density compared to text tokens. To address this, ...

Abstract: Large‐aperture antenna arrays promise fine angular resolution, but their dense layouts usually lead to prohibitive cost and design complexity. Sparse arrays present a compelling alternative, ...
