Credit: Zhanni Wu. Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published in Physical Review X, can rotate the polarization of an arbitrarily polarized incident wave without changing its axial ratio. […]

Principle and experimental set-up. a, Schematic representation of energy exchange between an unbiased photodiode and a planar surface located in the far-field of the photodiode. b, Schematic description of photonic refrigeration in the near-field. Simultaneous enhancement of photon transport from tunnelling of evanescent waves and suppression of luminescence from a […]

Electrons traveling between two layers of atomically thin material give off tiny bursts of electromagnetic waves in the terahertz spectral range. This glow, shown in red and blue, allowed researchers at SLAC and Stanford to observe and track the electrons’ ultrafast movements.

The new potentially portable laser could benefit a host of scientific applications, improve clocks for global positioning (GPS) systems, advance the detection of gravitational waves in space […]

At SLAC’s Linac Coherent Light Source, the researchers blasted an iron sample with laser pulses to demagnetize it, then grazed the sample with X-rays, using the patterns formed when the X-rays scattered to uncover details of the process.
