Studies on waves and instabilities in a plasma sheath formed on the outer surface of a space craft

摘要

Using the normal mode analysis, the number of possible modes is obtained in a magnetized inhomogeneous plasma sheath formed during the motion of a space craft which consists of negative ions (due to dust) along with the positive ions and the isothermal electrons. In addition to three propagating modes with phase velocities lambda(1), lambda(2), and lambda(3) such that lambda(1)
