How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

Abstract: We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional ...

Abstract: Spin angular momentum is a fundamental property of the propagating optical waves. In this work, we reveal a possibility of the continuous transition from the transverse spin angular momentum ...

Time-resolved measurements indicate that the switching is driven by a spin-polarized current passing through the subnanometer Ir interlayer. The magnetic properties of this model system may be tuned ...
