Notes:
The effect of a dc electric field on the spatial evolution of an external wave in a small cold beam–plasma system is investigated numerically. The wave enhancement is strongly dependent on the sign of detuning δω(=ω−ω0) (ω is the wave frequency and ω0 is the frequency of the most unstable mode). Negative detuning, i.e., negative δω, leads to an anomalous increase in the wave power as compared with the wave enhancement for zero or positive detuning. Weak collisions also can play an important role in limiting the wave enhancement.
