    • Nonlinear evolution of beam-plasma instability in inhomogeneous medium 

      Ziebell, Luiz Fernando; Yoon, Peter H.; Pavan, Joel; Gaelzer, Rudi (2011) [Artigo de periódico]
      The problem of electron-beam propagation in inhomogeneous solar wind is intimately related to the solar type II and/or type III radio bursts. Many scientists have addressed this issue in the past bymeans of quasi-linear ...

    • Particle-in-cell and weak turbulence simulations of plasma emission 

      Lee, Sang-Yun; Ziebell, Luiz Fernando; Yoon, Peter H.; Gaelzer, Rudi; Lee, Ensang (2019) [Artigo de periódico]
      The plasma emission process, which is the mechanism for solar type II and type III radio burst phenomena, is studied by means of particle-in-cell (PIC) and weak turbulence (WT) simulation methods. “Plasma emission” is meant ...

    • Plasma emission by counter-streaming electron beams 

      Ziebell, Luiz Fernando; Petruzzellis, Larissa Teixeira; Yoon, Peter H.; Gaelzer, Rudi; Pavan, Joel (2016) [Artigo de periódico]
      The radiation emission mechanism responsible for both type-II and type-III solar radio bursts is commonly accepted as plasma emission. Recently Ganse et al. suggested that type-II radio bursts may be enhanced when the ...

    • Plasma emission by nonlinear electromagnetic processes 

      Ziebell, Luiz Fernando; Yoon, Peter H.; Petruzzellis, Larissa Teixeira; Gaelzer, Rudi; Pavan, Joel (2015) [Artigo de periódico]
      The plasma emission, or electromagnetic (EM) radiation at the plasma frequency and/or its harmonic(s), is generally accepted as the radiation mechanism responsible for solar type II and III radio bursts. Identification and ...

    • Plasma emission by weak turbulence processes 

      Ziebell, Luiz Fernando; Yoon, Peter H.; Gaelzer, Rudi; Pavan, Joel (2014) [Artigo de periódico]
      The plasma emission is the radiation mechanism responsible for solar type II and type III radio bursts. The first theory of plasma emission was put forth in the 1950s, but the rigorous demonstration of the process based ...
