Abstract :
The aim of this paper is to show the propagation and polarization characteristic of some types of ELF electromagnetic emission below the cutoff frequency observed by DEMETER satellite. All the analysis is based on multi-component measurement method of electric and magnetic field in ELF band. According to the wave vector and planarity and ellipticity of polarization, we can judge the property of electromagnetic emission below the cutoff frequency. Then it will help us analysis the origin of emission further. In is this paper, only three types of emission are analyzed, and their emission origins are guessed.
