Abstract: In this article, an enhanced diffractive neural network is proposed for achieving metasurface holograms with high resolution, low noise, and uniform intensity. First, we prove the ...

Abstract: Current approaches for acoustic hologram generation are focused on phase-only methods. The few alternatives proposed for amplitude and phase holograms becomes cumbersome or not suitable for ...

Dec. 16, 2025 — If you search for hair dye on social media, you’ll mostly see inspo photos of women with brightly colored locks. But you’ll also find clips warning you that dying your hair isn’t so ...

In my lifetime of bad decisions, over-bleaching my hair is close to the top. My hair is fine and frizzy with an unpredictable wave pattern to begin with, and my addiction to being blonde has resulted ...

Holograms projected through mobile phones has always seemed like an idea straight out of science fiction. However, physicists have now built a compact optical device with the ability to project ...
