The book provides a broad overview of phenomena and effects in four main classes of radiophysical and physicotechnical systems: linear, nonlinear, parametric, and nonlinear-parametric. It presents a new paradigm for the existence of deterministic chaos in oscillating systems without external random influences. It describes effects of adaptive self-organization and synergistic grouping of systems into stable electromechanical formations. An adequate analytical framework has been developed for the wide range of problems under consideration, presented in a reader-friendly format that allows for its immediate application in research practice. Specific device and system schematics are provided, and a number of ground-based, airborne, and space-based applications are described.
