    • Effect of a large-amplitude circularly polarized wave on linear beam-plasma electromagnetic instabilities 
      Gomberoff, L.; Hoyos, J.; Brinca, A. L. (Blackwell Publishing Ltd, 2003)
      In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’ propagating parallel to the background magnetic field were shown to stabilize a moderately dense beam in a proton plasma against the ...
    • Electrostatic instabilities induced by large-amplitude left-hand polarized waves 
      Gomberoff, L.; Hoyos, J.; Brinca, A. L.; Ferrer, R. (Blackwell Publishing Ltd, 2004)
      We study the effect of a large-amplitude left-hand polarized wave on ion acoustic instabilities. We show that the presence of a finite amplitude left-hand polarized wave produces electrostatic instabilities above a threshold ...
    • Ion acoustic damping effects on parametric decays of Alfvén waves: Right-hand polarization 
      Gomberoff, L.; Gomberoff, K.; Brinca, A. L. (Blackwell Publishing Ltd, 2001)
      We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
    • Ion acoustic instability triggered by finite amplitude polarized waves in the solar wind 
      Gomberoff, L.; Hoyos, J.; Brinca, A. L. (Blackwell Publishing Ltd, 2005)
      [1] It is shown that ion-acoustic waves propagating along an external magnetic field and generated by parametric decays of circularly polarized finite amplitude waves have the properties of ion-acoustic waves observed ...
    • New parametric decays of proton beam-plasma electromagnetic waves 
      Gomberoff, L.; Gomberoff, K.; Brinca, A. L. (Blackwell Publishing Ltd, 2002)
      Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
    • On the generation of totem pole emissions 
      Brinca, A. L.; Romeiras, F. J.; Gomberoff, L.; Marçal, M. H. (Blackwell Publishing Ltd, 2004)
      Understanding of the generation of electron cyclotron harmonic waves by almost monoenergetic perpendicular ion beams contributes to the interpretation of the totem pole (TP) emissions observed at the Earth's magnetopause ...
    • On the stability of perpendicular particle drifts in cold magnetoplasmas 
      Brinca, A. L.; Romeiras, F. J.; Gomberoff, L. (Blackwell Publishing Ltd, 2002)
      Assessment of the stability of perpendicular particle drifts in cold magnetoplasmas shows that their free energy can stimulate wave activity under various circumstances that include nonoscillatory (aperiodic, purely growing) ...
    • On wave generation by perpendicular currents 
      Brinca, A. L.; Romeiras, F. J.; Gomberoff, L. (Blackwell Publishing Ltd, 2003)
      Previous assessment of the stability of perpendicular particle drifts in cold magnetoplasmas showed that their free energy could stimulate wave activity under various circumstances that included nonoscillatory (aperiodic, ...
    • Stimulation of electron Bernstein modes by perpendicular ion beams 
      Brinca, A. L.; Romeiras, F. J.; Gomberoff, L. (American Geophysical Union, 2003)
      This investigation studies the characteristics of electron cyclotron harmonic waves generated by almost monoenergetic perpendicular ion beams. Its motivation is twofold: (1) the new type of free energy source, beams made ...
