contents Behavior of linear beam-plasma instabilities in the presence of finite amplitude circularly polarized waves L. Gomberoff J. Hoyos A. L. Brinca Física, Astronomía y Matemáticas We review the effect of finite amplitude circularly polarized waves on the behavior of linear ion-beam plasmainstabilities. It has been shown that left-hand polarized waves can stabilize linear right-handed instabilities [1].It has also been shown that for beam velocities capable of destabilizing left-handed waves, left-hand polarizedlarge amplitude waves can also stabilize these waves. On the other hand, when the large amplitude wave isright-hand polarized, they can either stabilize or destabilize right-handed instabilities depending on the wavefrequency and beam speed [2]. Finally, we show that the presence of large amplitude left-hand polarized wavescan also trigger electrostatic ion-acoustic instabilities by forcing the phase velocities of two ion acoutic waves to become equal, above a threshold amplitude value. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434809 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.34
