    Research output: Contribution to journalJournal articleResearchpeer-review


    The collapse of electrostatic upper hybrid waves in weakly magnetized plasmas is considered with particular attention to include dispersive low-frequency waves in the equations governing the ion dynamics. Considering a magnetic-field aligned cylindrical collapse we demonstrate that a magnetic field can delay or even prevent a collapse in comparison with the unmagnetized case.
