Research ArticleOpen accessIn the keywordsGeneral Properties of 3/2ω0 and 2ω0 Harmonics Emission from Laser Driven PlasmasA.S.A. Dib, A.H. BelbachirUsing a simple model based on the conversion of electron plasma waves into electromagnetic waves through a process of parametric interaction of four waves, the general properties of the 3/2ω0 emission and the 2ω0 emission generated by the interaction of a Gaussian laser pulse with homogeneous plasma are studied. Some known characteristics of these emissions are reproduced within this model … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcceleration and Particle Field Interactions of Cosmic Rays: FormalismA. Tawfik, A. Saleh, M.T. Ghoneim, A.A. HadyThe origin and acceleration theories of Ultrah High Energy Cosmic Rays (UHECRs) are still mesterious problem in modern physics and astrophysics. The acceleration of ultra high energy cosmic rays is conjectured to occur through interactions with electromagnetic fields in different astrophysical objects, like magnetic matter clumps, besides the well-known shock waves and elastic Fermi mechanisms. Based on this model, a … …Physics International, Vol. 3, Issue 2 · 18 May 2013 · 7,458 accessesView PDFCite
