Electromagnetic helicity is a scalar property corresponding to the projection of the photons’ spin along the momentum direction. In free-space, or in a bulk medium, it can have two eigenvalues – ...

Maxwell's equations are sort of a big deal in physics. They're how we can model an electromagnetic wave—also known as light. Oh, it's also how most electric generators work and even electric motors.

Also, the same metamaterial can process multiple waves simultaneously: “Waves can pass through each other, giving you a parallel system,” explains Engheta. To test their ideas, the researchers ...
