WebHysell and Nossa argued that wave trapping below the second gyroharmonic frequency can occur if finite parallel wave numbers are allowed for the upper hybrid waves, since finite k ì has the effect of introducing a lower cutoff frequency below 2Ω e. The same principle should also permit wave trapping near gyroharmonic frequencies.
