Pk. Shukla et al., AMPLITUDE-MODULATION OF KINETIC ALFVEN WAVES AND THE FORMATION OF NONLINEAR STRUCTURES, Physics letters. A, 239(6), 1998, pp. 369-372
The theory of the amplitude modulation of finite amplitude kinetic Alf
ven waves in a medium beta plasma is re-examined and extended, The mod
ulational and filamentational instabilities as well as associated loca
lized structures in magnetic field and plasma density are investigated
. The relevance of our investigation to coherent nonlinear structures
in the ionospheric plasma is pointed out. (C) 1998 Elsevier Science B.
