Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Report contains calculation of the radioemission of semi-restricted thin modulated electron beam injected from the spacecraft board into the ionosphere plasma along the geomagnetic field. Radioemission appears due to the synchronism between the electric current wave of modulated beam and electromagnetic eigenmode of the anisotropic plasma. Radiation pattern for whistlers’ frequencies is formed as a result of the interference between three independent modes with the same frequency and different wavelengths. Consequently, Pointing vector angular dependence is oscillatory at small angles. At larger angles, the radiation pattern has a sharp maximum near the resonant cone. |
