Tidskriftsartikel (refereegranskat)abstract
- Lower hybrid wave cavities detected by the Freja satellite are analyzed. On the basis of simple statistical arguments by use of signals from two density probes, it is possible to obtain rather general results concerning the individual shapes of these cavi

Tidskriftsartikel (refereegranskat)abstract
- A large number of narrow density cavities (50 m wide in the direction perpendicular to the magnetic field) are observed by the FREJA satellite. These cavities are correlated with electric field enhancements in the frequency range of Lower Hybrid waves. By
