… The conventional beamformer is susceptible to poor responses when interferers appear
in the signal beam’s side lobes: so-called side lobe limited behavior. By taking into account …

… Similarly, the green conical shape covers the LoS, enabling the received photons of the
signal beam to fall on the photodetectors. The incident beam passes through an AP and is then …

… an orbital angular momentum mode shifting recirculating delay loop (OAM-SL) in simulation
using Kirchhoff-Fresnel diffraction (KFD) and the delays applicability for RF signal beam …

… Abstract: When a signal beam propagates through the atmosphere, it is affected by turbulence.
The Airy beam, with its characteristics of diffraction-free propagation, selfhealing, and self-…

… (OAM) transfer from probe to 9 generated signal beam. The effect of the relaxation process is
… the OAM nature of the generated 14 signal beam. The physical explanation is given for the …

… The highest output power of 8.9 W was reached for the 1750 nm signal beam with 19%
conversion efficiency and the respective 2500 nm idler beam power was 6.2 W with 13% …

… 1, the solid and dashed lines show the signal-beam profiles with two different frequencies in
the … It was assumed that the signal beam propagated in the z-direction and the spatial profile …

… Second, the signal beam must be angled to apply a linear tilt across the wavefronts. We see
the flattened wavefronts of the reference beam and the tilted wavefronts of the signal beam …

… for the signal beam for the different cavity configurations at a pump power of 34 $\mathrm
{W}$. The beam quality of the idler beam behaves in analogy to the signal beam but the beam …

… number $\bar {c}_{\rm s}$ of photocounts in the signal beam in fact means the subtraction of
the same number of photons from the signal beam and we then have $n_{\rm i} - n_{\rm s} = \…
