This book delves into the complex world of wave propagation in plasmas, a topic that has fascinated scientists since the study of radio waves in the ionosphere. The author goes beyond the common approximations used in this field, such as geometric optics and plane stratified medium models, to examine the fundamental equations governing wave behavior in a cold plasma. The book uses electromagnetic potentials to formulate the problem, resulting in a sixth-order system of partial differential equations. These equations reveal intriguing properties of wave propagation in plasmas, including transitions from elliptic to hyperbolic behavior at key resonance surfaces like the lower and upper hybrid resonances, and at the ion and electron cyclotron resonances. These transitions, which are uncommon in other areas of physics, highlight the unique nature of waves in plasmas. The author also explores the implications of these transitions for energy absorption and heating within the plasma. The book then delves into the specific case of wave propagation in axisymmetric plasmas, simplifying the problem to a fourth-order system. This investigation into the axisymmetric equilibrium case allows the author to explore wave propagation at frequencies near both the ion cyclotron frequency and the ion plasma frequency. The book concludes with an in-depth analysis of wave propagation near the lower hybrid resonance surface. The author distinguishes between two scenarios: one where the resonance surfaces coincide with flux surfaces, leading to heating along the entire resonance surface, and another where they do not coincide, resulting in heating only at points of tangency between the surfaces. This book provides a rigorous exploration of wave propagation in plasmas, offering a deeper understanding of the complex phenomena at play and providing valuable insights for the field of plasma physics.
