| Zusammenfassung |
| Banded emissions are frequently observed in planetary magnetospheres. Owing to
the intra-harmonic character of the measured frequencies and the fact that they
are most often observed near the magnetic equator (suggesting near perpendicular
propagation), they are generally attributed to Bernstein waves. A 1D spatial electrostatic
Particle-in-Cell (PIC) simulation was performed for a magnetised plasma composed of
electrons with a Maxwellian velocity distribution and massive ions. Wave propagation
perpendicular to the magnetic field, k -¥ B, was considered and the resulting dispersion
relations revealed a set of harmonics. The lower harmonics were found to be only
weakly damped while higher harmonics incurred progressively stronger damping. |
