Holographic reconstruction is troubled by the phase-conjugate wave front arising from Hermitian
symmetry of the complex field. The so-called twin image obfuscates the reconstruction …

Based on the extended Huygens–Fresnel diffraction integral, the expressions for the
average intensity and the effective size of Laguerre–Gaussian and Bessel–Gaussian Schell-model …

The Orbital-Angular-Momentum (OAM)-carrying radio waves may provide extra rotational
degree of freedom, which may potentially increase channel capacity and spectrum efficiency …

In this paper, the capacity of a communication system based on orbital angular momentum (OAM)
multiplexing is thoroughly studied and compared with the conventional multiple input …

Gamma-Ray Integrated Detectors (GRID) mission is a student project designed to use
multiple gamma-ray detectors carried by nanosatellites (CubeSats), forming a full-time all-sky …

An orbital angular momentum (OAM)-based in-band full-duplex radio system for line-of-sight
communications is studied for the first time, where the OAM beams work as the carriers of …

GRB 230812B, detected by the Gamma-Ray Integrated Detectors constellation mission, is
an exceptionally bright gamma-ray burst (GRB) with a duration of only 3 s. Sitting near the …

Based on the generalized spectral model for non-Kolmogorov atmospheric turbulence,
analytic expressions of the scintillation index (SI) are derived for plane, spherical optical waves …

Abstract Effects of atmospheric turbulence tilt, defocus, astigmatism and coma aberrations
on the orbital angular momentum measurement probability of photons propagating in weak …

The propagation behavior of the multi-Gaussian Schell-model source through ABCD optical
systems and its spreading in the turbulent atmosphere are investigated. We obtain the …
