This repository contains the public release of the Phase-Gradient Cavitation Model. The model is constructed using conventional mathematical tools (fluid analogy, divergence, gradient behavior, and ...

Huygens antennas exploit electric-magnetic field coupling for directional, low-loss radiation, driving advances in communications, sensing, and nanophotonics. First, you have your simple antennas – ...

Since the Generalized Snell's Law (GSL) was proposed, planar metasurfaces have achieved remarkable progress in optical and electromagnetic wavefront manipulation by leveraging phase gradients. The ...

The powerful light field manipulation capability of metasurfaces offers a novel development perspective for the quantum precision measurement. By applying the phase-gradient metasurface (PGM) to ...

Researchers built a fingernail-sized magnetometer using metasurfaces that measures fields billions of times weaker than Earth's, opening new paths for quantum sensing. At the heart of the sensor is an ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

New metasurfaces with nanoantennas could replace lenses and enhance AR, VR, LiDAR, and more by precisely controlling light. (Nanowerk News) Antennas receive and transmit electromagnetic waves, ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The number of ways to harvest energy that would otherwise go unused and wasted is extraordinary. To cite a few of the many examples, there’s the heat given off during almost any physical or electronic ...

Optical metamaterials have fascinated physicists and engineers for decades. While theoretical discussions began in the 1940s, significant experimental progress only occurred in the last 20-30 years, ...

Abstract: Periodic phase-gradient metasurfaces (PGM) have been successfully used to produce anomalous reflection and refraction for small and moderate bending angles, but are not capable of ...

Abstract: Gradient metasurfaces, or ultrathin optical components with engineered transverse impedance gradients along the surface have recently been demonstrated to provide control of the phase of ...
