摘　　要：Electromagnetic （EM） behavior and instability resulting from the interaction between EM wave and plasma wave are analyzed based on linear perturbation theory. It is shown that the instability is caused by the the coupling between high frequency electromagnetic field and electron transverse oscillation derived from the deflection of electron longitudinal oscillation due to self-produced magnetic field. The influences of the self-produced magnetic field and plasma density on the ihstability are studied. In addition, characteristics of EM wave propagation at different angles are investigated. The present results are of significance to new type plasma radiation source, ion accelerator and plasma diagnostic techniques.Electromagnetic （EM） behavior and instability resulting from the interaction between EM wave and plasma wave are analyzed based on linear perturbation theory.
