The well-defined orbital angular momentum (OAM) of rotating cavity modes operating near the cutoff frequency excited by gyrating electrons in a high-power electron cyclotron maser (ECM)—a gyrotron—has been derived by photonic and electromagnetic wave approaches. A mode generator was built with a...
Momentum explains the multiplication ofvelocityand mass can give rise to the momentum of a body. When a body is in motion with a certain amount of mass, it possesses momentum. Well, angular momentum and momentum both are different by their different functionality. Electrons are always revolving ...
Angular momentumElectric dipole momentsElectromagnetic interactionsVector fieldsWe are now in a position to calculate the full angular functions for the general central force problem, using the laddering techniques for the θ equation to construct the full set of angular functions Θ(θ) via the ...
We propose and numerically demonstrate a conversion and multicasting scheme of orbital angular momentum (OAM) states by using N-core supermode fiber (NCSF), where the topological charges of converted OAM states mainly depend on the injected OAM state and the number of fiber cores. The conversion...
Is angular momentum conserved in a pendulum? A direct consequence of equation (4) is that,if there are no external torques on a system, its angular momentum is conserved. A simple pendulum shown below contains a torsional spring at the pivot which creates a restoring torque proportional to θ...

The evolution of orbital angular momentum distributions within the radiative parton model is studied. We use different scenarios for the helicity weighted parton distributions and consider a broad range of input distributions for orbital angular momentum. In all cases we are lead to the conclusion that...
Here is the relevant equation (17.3.14) for the angular momentum L from your cited paper: This is the same as the result I calculated for the two body angular momentum using circular orbits. Note that r0 "is a constant (known as the semilatus rectum)"(semimajor axis in English). ...

Orbital Angular Momentum (OAM), as a property of Electromagnetic (EM) fields has recently been proposed for Radio and Microwave communications. This paper investigates a new class of OAM radiation patterns for Radio and Microwave applications, namely, Quasi-OAM radiation patterns, induced by a propo...
