Electromagnetic metamaterials with negative physical parameters such as negative dielectric constant and negative magnetic permeability have attracted widespread attention in the academic community. In 2010, they were praised ...
A collaborative research team led by Interim Head of Â鶹ÒùÔºics Professor Shuang Zhang from The University of Hong Kong (HKU), along with National Center for Nanoscience and Technology, Imperial College London and University ...
Robots and autonomous cars will have eyes that see much more than the human eye is capable of, a review of the growing field of meta-optics has found.
Researchers from Northwestern University have made a significant advance in the way they produce exotic open-framework superlattices made of hollow metal nanoparticles.
The global spread of COVID-19 has highlighted the importance of rapid, accurate, and easy sensing of viruses and diseases. Recently, researchers have been exploring on-chip sensing technologies to tackle these emerging challenges. ...
We all look in the mirror at least once a day to see our reflection. Mirrors are used not only in daily life but also in cutting-edge technologies such as semiconductor processing and high-resolution displays. Recently, a ...
University of Oregon physicists have developed a new method to manipulate sound—stop it, reverse it, store it and even use it later—in synthetic composite structures known as metamaterials.
One of the challenges of optical microscopy is to continually increase the imaging power, or resolution. In the past three hundred odd years, scientists have been building ever-better microscopes. The limit, for a long time, ...
Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also ...
In materials science, achromatic optical components can be designed with high transparency and low dispersion. Materials scientists have shown that although metals are highly opaque, densely packed arrays of metallic nanoparticles ...
