Very Low Frequency emissions are the audio-frequency signals generated by the wave particle interaction in the magnetosphere. These waves propagate in the whistler mode from the source region to the observation point. Accurate analysis and interpretation of the dynamic spectra yield information about composition and structure of the intervening media alongwith the generation mechanism. We have observed hiss, periodic hiss, chorus emission and triggered emissions during routine recording of whistler waves but spectrogram of the discrete VLF emissions are not presented in this paper. Details of theoretical computation are presented. In our computation we have shown that the non-linear theory of wave-particle interaction could explain partly the observed spectra. We have computed resonant electron energy for different pitch angle for L = 2 and 4.5 and Bunching time, trapping time, etc are also computed. The computed results are in good agreement with those reported by other workers. [ABSTRACT FROM AUTHOR] |
