AbstractThe conversion of Langmuir waves into electromagnetic radiations is an important mechanism of Type Ⅲ solar bursts.Langmuir Waves(LW) can be easily excited by electron-beam instabilities,and they can become backward propagating throuth the wave-wave interaction.Generally,the backward-propagating LW are very important for the second-harmonic waves of Type Ⅲ solar bursts.In this paper we pay particular attention to the mechanism of the backward-propagating LW as revealed through numerical simulations based on the Partical-in-Cell(PIC) method.We found that ions play a key role to excite the backward-propagating LW,with draw much of their energy from the scattering of the forward-propagating LW.Moreover,an electron beam can hardly generate backward-propagating LW directly,but may directly amplify second-harmonic forward-propagating LW.
