Fig. 2.From: Giant pulsations as modes of a transverse Alfvénic resonator on the plasmapauseExample of the behavior of the toroidal f T and poloidal f P eigenfrequencies (principal harmonics) with finite plasma pressure at medium geomagnetic activity. The filled areas are the transparent regions. The eigenfrequencies are calculated for the model plasma parameters in Schäfer et al. (2008).Back to article page
