摘要：

Observations of non-linear second harmonic (SH) in various waves have recently been reported by several studies. However, the quantitative relation of the amplitudes between the fundamental wave (FW) and the SH has not been derived and verified yet. In this letter, the relation equations for the FW and the SH are simplified under the cold plasma assumption, which is reasonable in the inner magnetosphere. The quantitative relation of the amplitudes between the FW and the SH of the electromagnetic ion cyclotron wave is theoretically derived and verified through 1-D hybrid simulations. The quantitative influences of the FW frequency and wave normal angle on the SH excitation mechanism are obtained.
