High-informative version of nonlinear transformation of Langmuir waves to electromagnetic waves

Abstract

AbstractThe concept of informativeness of nonlinear plasma physical scenario is discussed. Basic principles for heightening the informativeness of plasma kinetic models are explained. Formerhigh-informative correlation analysis of plasma kinetics(Erofeev, V. 2011High-Informative Plasma Theory, Saarbrücken: LAP) is generalized for studies of weakly turbulent plasmas that contain fields of solenoidal plasma waves apart from former potential ones. Respective machinery of plasma kinetic modeling is applied to an analysis of fusion of Langmuir waves with transformation to electromagnetic waves. It is shown that the customary version of this phenomenon (Terashima, Y. and Yajima, N. 1963Prog. Theor. Phys.30, 443; Akhiezer, I. A., Danelia, I. A. and Tsintsadze, N. L. 1964Sov. Phys. JETP19, 208; Al'tshul', L. M. and Karpman, V. I. 1965Sov. Phys. JETP20, 1043) substantially distorts the picture of merging of Langmuir waves with long wavelengths (λ ≳c/ωpe).
