Orbital Angular Momentum (OAM): The quantised component of angular momentum arising from the spatial distribution and helical phase structure of an electron beam.

In this communication, an orbital angular momentum (OAM) mode-reconfigurable antenna based on a uniform circular array (UCA) is presented. To realize multiple switchable operating states while ...

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 multiple-in-multiple-out (MIMO) ...

Objective: The biomechanics of the head for punches to the jaw and the risk of head injury from translational and rotational acceleration were studied. Methods: Seven Olympic boxers from five weight ...

Angular momentum is the product of two quantities known as angular velocity and moment of inertia. Angular velocity is merely velocity measured in degrees, or radians-per-second, rather than ...

Angular momentum and the spin vector in Dirac's theory 301 11. The kinetic energy of an electron 304 12. The second intrinsic degree of freedom of the electron 305 13. Second-order equations 308 ...

The dynamics of electron transfer at the dye–titania and titania–electrolyte interfaces is investigated in two post-sensitization processes: (i) atomic layer deposition of blocking alumina coating and ...

Nitrogen-vacancy (NV) centers in diamond are reliable single-photon emitters, with applications in quantum technologies and metrology. Two charge states are known for NV centers, NV0 and NV–, with the ...
