Optical 'watermills' control spinning light

Scientists at King's have built on research they conducted last year to achieve previously unseen levels of control over the travelling direction of electromagnetic wave in waveguides and proved that the process works equally ...

Charging electric cars efficiently inductive

We already charge our toothbrushes and cellphones using contactless technology. Researchers have developed a particularly efficient and cost-effective method that means electric cars could soon follow suit.

Transfering magnetic fields across long distances

A Catalan, German and Austrian group of physicists has developed a new technology to transfer magnetic fields to arbitrary long distances, which is comparable to transmitting and routing light in optical fibers. Oriol Romero-Isart ...

Twisting the light away using ultrasmall holes

A new study shows that light transmitted through apertures smaller than the wavelength of light go through a radical change, splitting into two symmetrical counter-rotating polarisations.
