摘要: The possibility of using a modulated electron beam injected in magnetized plasma as low frequency antenna (frequency lower than the gyrofrequency) is explored. physical mechanism proposed to insure this property spontaneous coherent emission. Derivation power lost by done with emphasis on particular conditions named "focalization condition" encountered whistler range frequency. In conclusion limits model are discussed together perspectives opened work.
