• Lightwaves consist of both an electric and a magnetic field, which oscillate perpendicular to each other. Polarization refers to the direction in which the electric field oscillates.
  • Normally, the polarization is perpendicular to the direction in which the light is moving; . But things were different when the researchers took the beam they’ve passed through the q plate and focused it through a microscope lens onto a spherical gold nanoparticle.
  • Karimi says eliciting this new behavior from light might help physicists understand more about the fundamental nature of optics and physics. It might have a practical application as well. If they can shape a light beam in three dimensions, they could conceivably use that ability to fabricate 3-D structures in the sort of photolithography processes used to build electronic circuits.
