A review of laboratory investigations of space plasma waves

A rich variety of wave phenomena exist in virtually every region of the geospace environment. These range from simple sound waves in the neutral terrestrial atmosphere to plasma waves in the ionosphere and magnetosphere. Knowledge of the various wave signatures and driving mechanisms gives insight into the local conditions, not only at the instant that the waves are observed, but also into how the conditions may evolve in time. Comprehensive, controlled investigations of the physics associated with these waves are difficult to accomplish through in situ methods alone. Consequently, properly scaled laboratory experiments can offer a complementary approach to investigating the wave dynamics. In this work, we present a review of several key wave modes found in the various regions, with a particular emphasis on significant contributions of laboratory investigations toward the present understanding of the wave dynamics.
