In this paper, we design a 38 GHz orbital angular momentum (OAM) antenna consisting of a horn antenna, a spiral phase plate (SPP), and a biconvex lens. The results show that this antenna design scheme ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Non-Hermitian topological systems exhibit a range of unique phenomena that are absent in their Hermitian counterparts.

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a ...

Multifrequency electron paramagnetic resonance spectroscopy on oriented single crystals of magnetically dilute Gd(III) ions in Gd0.004Y0.996(trensal) is used to determine the Hamiltonian parameters of ...

LE BOURGET–Here at the Paris Air Show, Dassault Aviation is exhibiting a small-scale model of the Vortex—a French acronym for orbital vehicle for transportation and exploration—a reusable ...

In addition, our study shows that the total angular momentum of the incident circularly polarized vortex beam can be conserved, where the far field of the transmitted beam contains both left- and ...
