Web1 de ago. de 2024 · The self-focusing phenomenon disappears when the initial coherence is high enough or the oceanic turbulence is strong. The area of high coherence appears in the center and along two diagonal lines. With increasing turbulence, the coherence area reduces gradually along one diagonal line and is retained along the other one. portobelloprimary.eschools.co.uk https://collectivetwo.com

Web12 de dez. de 2024 · An electron beam at a relativistic velocity has a self-focusing effect due to the magnetic field created by the electron beam itself and the increase in electron mass, which reduces the divergence of the electron beam due to the SC effect. Therefore, the SC effect mainly occurs within the acceleration field in an electron gun. Weberences on self-focusing and self-trapping, see [26]. A unied approach to self-action effects is given in [27]. In our review, we take an approach which is opposite to much of the historical sequence. We will rst discuss instabilities, then beam self-focusing, and nally self-trapping. 4 Nonlinear polarization and the nonlinear refractive index
