Two shells of counterstreaming plasma, and the filamentation mode with wave vector perpendicular to the streaming direction.
Filamentation instability in a counterstreaming plasma for three values of electron streaming speed: (solid line), (dashed line), and (dotted line). The coordinates are and .
Weibel instability in a bi-Maxwellian plasma for three values of the electron anisotropy : (solid line), (dashed line), and (dotted line). The coordinates are and .
The cumulative effect (growth rates with solid line) for the Weibel and filamentation instabilities in a counterstreaming electron plasma, with , and a bi-Maxwellian distribution, with , and . The growing rates of the Weibel instability (dotted line) and filamentation instability (dashed line) are shown using the same parameters. ( and .)
The same as in Fig. 4, but with , , and .
The same as in Fig. 4, but with , , and . Weibel instability does not exist along the propagation direction of filamentation instability, but the unstable mode is supressed (solid line) by the cumulative effect.
