The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, ...
Over the past decade, metasurfaces deploying two-dimensional artificial nanostructures have emerged as a groundbreaking platform to manipulate light across various degrees of freedom. These metasurfaces exhibit significant ...
Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown ...
Dielectric metasurfaces represent one of the cutting-edge research and application directions in optics. They not only possess the advantage of low loss but also enable the realization of device thicknesses at subwavelength ...
A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics departments at the University ...
Information technology plays a pivotal role in contemporary society, influencing aspects such as social communication, audio-visual entertainment in daily life, and the integration of cloud computing and the Internet of Things ...
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg ...
Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers ...
A multi-institutional team of optoelectronic and materials engineers in China has developed a type of metamaterial that is nearly invisible across visible light, microwave and infrared spectra. In their paper, published in ...
Traditional microelectronic architectures, with transistors to control electrical currents along wires, power everything from advanced computers to everyday devices.
