Orbital angular momentum (OAM) mode multiplexing has the potential to achieve high spectrum-efficiency communications at the same time and frequency by using orthogonal mode resource. However, the ...

This letter presents an effective optimization synthesis approach for orbital angular momentum (OAM) beams with low sidelobe and high mode purity through antenna array complex excitation optimization.

The product of each of thse masses into its velocity is the same, for 1X1=1, 2X^=1, &c and this product of the mass into the velocity of a body is called its momentum, moving force, or quantity of ...
