Point and shoot: the polarization camera is about two centimetres in diameter and uses a metasurface with an array of nanopillars. (Courtesy: Eliza Grinnell/Harvard SEAS) A compact and simple camera ...
A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...
A beam transformed: Optical transforms like tight focussing and total internal reflection, which gives rise to an evanescent field, can lead to out-of-plane polarization components and transverse spin ...
