The Nobel Prize in Chemistry 2014 was awarded for the development of super-resolved fluorescence microscopy. Inspired by this work, scientists at Institute of Photonic Chips (IPC), University of ...

(Phys.org)—A team of researchers working at the University of Liverpool in the U.K. has created some interesting looking disks using some of the unique and exciting properties of light. In their paper ...

Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...

We report zero-th and high-order acoustic Bessel beams with broad depth-of-field generated using acoustic holograms. While the transverse field distribution of Bessel beams generated using traditional ...

A new beam pattern could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- even etch new properties onto their surfaces. A ...
