Modeling AGW and PEMW in inhomogeneous atmosphere and ionosphere

The paper discusses some recently solved problems of wave dynamics in the ionosphere as well as the methods developed for analysis and solving of them: (1) a possibility of waveguiding AGW in upper atmosphere; (2) resonant atmospheric gravity waves (AGW) in inhomogeneous atmospheric waveguide; (3) planetary electromagnetic waves (PEMW) in the system “Lithosphere-Atmosphere Ionosphere-Magnetosphere (LAIM)” and means for waves detection and data processing. The paper also discusses the prospects of further studies and emphasizes the role of PEMW as indicators of ionospheric processes.
