Theory and observation of electromagnetic ion cyclotron triggered emissions in the magnetosphere

Original language description

We develop a nonlinear wave growth theory of electromagnetic ion cyclotron (EMIC) triggered emissions observed in the inner magnetosphere. We first derive the basic wave equations from Maxwell's equations and the momentum equations for the electrons andions. We then obtain equations that describe the nonlinear dynamics of resonant protons interacting with an EMIC wave. The frequency sweep rate of the wave plays an important role in forming the resonant current that controls the wave growth. Assuming anoptimum condition for the maximum growth rate as an absolute instability at the magnetic equator and a self?sustaining growth condition for the wave propagating from the magnetic equator, we obtain a set of ordinary differential equations that describethe nonlinear evolution of a rising tone emission generated at the magnetic equator.
