Bernstein waves are electrostatic waves originating in plasmas with an external magnetic field. These waves are detected from data measured by spacecraft in the Earth’s magnetosphere (e.g., by CLUSTER spacecraft and also they are observed in laboratory experiments (e.g., ). Bernstein modes can be coupled with electromagnetic waves on density irregularities along magnetic field-lines and electromagnetic waves can scatter to electrostatic waves and vice versa. Such coupling was recently numerically studied by Eliasson et al.. In our study we focus on Particle-In-Cell (PIC) simulations of conversion of electrostatic Bernstein modes to free space electromagnetic mode. This possible mechanism was proposed in as a possible source of measured electromagnetic waves trough the region outside the plasmapause.
