Abstract: A novel 2-bit coding metasurface for terahertz beam steering is proposed here. By fractionally dividing the phase gradient distribution, a higher-precision beam steering has been implemented ...

Abstract: We present a 2-bit coding array that features high beam-pointing accuracy and side-lobe-level (SLL) performance for wide-angle beam scanning. By symmetrically exciting a circular ring patch ...

Andrej Karpathy led AI at Tesla and cofounded OpenAI. He also also coined the term "vibe coding." Reflecting on the last year, Karpathy wrote that vibe-coding has produced a new type of code that is ...
