An international team of astronomers has analyzed the data from long-term multiwavelength monitoring of a distant blazar ...

Abstract: This letter proposes a design scheme that combines a quantized phase-gradient focusing metasurface with a rectifying antenna to enhance the power conversion efficiency (PCE) in radio ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

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 ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...

A study published in Advanced Optical Materials describes a wireless power transfer (WPT) system that integrates an electromagnetic wave-focusing metasurface lens with a microstrip antenna and a ...

New technology that uses light's color and spin to display multiple images. From smartphones and TVs to credit cards, technologies that manipulate light are deeply embedded in our daily lives, many of ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...
