Book Description
Nonlinear effects in the ionosphere (cross modulation of radio waves) have been known since the 1930s. Only recently, however, has the rapid increase in the power and directivity of the radio transmitters made it possible to alter the properties of the ionosphere strongly and to modify it artificially by applying radio waves. This has revealed a variety of new physical phenomena. Their study is not only of scien tific interest but also undisputedly of practical interest, and is presently progressing very rapidly. This monograph is devoted to an exposition of the present status of theoretical research on this problem. Particular attention is paid, naturally, to problems in the development of which the author himself took part. It is my pleasant duty to thank V. L. Ginzburg, L. P. Pitaevskii, V. V. Vas'kov, E. E. Tsedilina, A. B. Shvartsburg, and Va. S. Dimant for useful discussions and for valuable remarks during various stages of the work on the problem considered in this book. Contents 1.

Book Description
Investigated was a very important mechanism for the decay of upper hybrid waves into electron Bernstein waves. This mechanism operates only in a very narrow resonance region around the harmonics of the electron cyclotron frequency. The researchers calculated the width of these resonances and compared the analytical results with experimental observations. They found very good agreement with all available data. They found a simple mechanism for the generation of upper hybrid waves from the pump made by direct conversion. Simple estimates indicate how extremely large amplitude waves can be generated.

Book Description
During the past few decades, various investigations on nonlinear heating of the auroral region of the ionosphere and problems related to lower ionosphere are resulted in opening up a new dimension towards the study of various physical processes and also on the characteristics of different parameters of Atmospheric Electricity within the middle and lower ionosphere. This book embodies the results of some of the investigations in these areas. Some modeling works have been performed and results are compared with experimental data of other researchers. Some experiments were undertaken based on the own experimental arrangements from Kolkata and Agartala, India centers during disturbed ionospheric and atmospheric conditions and results are presented here. There are other areas to be explored and further studies are contemplated to gather more information. I shall deem my labour amply rewarded if the matters presented in the book prove to be useful and worthy to the scientific community in this field.

Book Description
The Dynamical Ionosphere: A Systems Approach to Ionospheric Irregularity examines the Earth’s ionosphere as a dynamical system with signatures of complexity. The system is robust in its overall configuration, with smooth space-time patterns of daily, seasonal and Solar Cycle variability, but shows a hierarchy of interactions among its sub-systems, yielding apparent unpredictability, space-time irregularity, and turbulence. This interplay leads to the need for constructing realistic models of the average ionosphere, incorporating the increasing knowledge and predictability of high variability components, and for addressing the difficulty of dealing with the worst cases of ionospheric disturbances, all of which are addressed in this interdisciplinary book. Borrowing tools and techniques from classical and stochastic dynamics, information theory, signal processing, fluid dynamics and turbulence science, The Dynamical Ionosphere presents the state-of-the-art in dealing with irregularity, forecasting ionospheric threats, and theoretical interpretation of various ionospheric configurations. Presents studies addressing Earth’s ionosphere as a complex dynamical system, including irregularities and radio scintillation, ionospheric turbulence, nonlinear time series analysis, space-ionosphere connection, and space-time structures Utilizes interdisciplinary tools and techniques, such as those associated with stochastic dynamics, information theory, signal processing, fluid dynamics and turbulence science Offers new data-driven models for different ionospheric variability phenomena Provides a synoptic view of the state-of-the-art and most updated theoretical interpretation, results and data analysis tools of the "worst case" behavior in ionospheric configurations
