دانلود کتاب Coupled-Oscillator Based Active-Array Antennas

Describing an innovative approach to phased-array control in antenna designThis book explores in detail phased-array antennas that use coupled-oscillator arrays, an arrangement featuring a remarkably simple beam steering control system and a major reduction in complexity compared with traditional methods of phased-array control. It brings together in one convenient, self-contained volume the many salient research results obtained over the past ten to fifteen years in laboratories around the world, including the California Institute of Technology's Jet Propulsion Laboratory.The authors examine the underlying theoretical framework of coupled-oscillator systems, clearly explaining the linear and nonlinear formalisms used in the development of coupled-oscillator arrays, while introducing a variety of state-of-the-art methodologies, design solutions, and tools for applying this control scheme. Readers will find:Numerous implementation examples of coupled-oscillator array prototypesA continuum model that permits application of diffusion theory to the analysis of phase dynamicsA demonstration of the array behavior through experimental results that validate the linearized theoryExamples of how incorporating coupling delay restores causality, including the latest published resultsGuidance on how to accurately analyze and optimize coupled-oscillator arrays using modern simulation toolsA review of current developments, including the design of compact couple-oscillator array antennasComplete with 150 diagrams and photographs, Coupled-Oscillator Based Active-Array Antennas is a highly useful tutorial for antenna designers and a valuable reference for researchers and engineers wishing to learn about this cutting-edge technology.Content: Chapter 1 Introduction—Oscillators and Synchronization (pages 1–26): Chapter 2 Coupled?Oscillator Arrays—Basic Analytical Description and Operating Principles (pages 27–66): Chapter 3 The Continuum Model for Linear Arrays (pages 67–102): Chapter 4 The Continuum Model for Planar Arrays (pages 103–137): Chapter 5 Causality and Coupling Delay (pages 139–173): Chapter 6 Experimental Validation of the Theory (pages 175–215): Chapter 7 Perturbation Models for Stability, Phase Noise, and Modulation (pages 217–261): Chapter 8 Numerical Methods for Simulating Coupled?Oscillator Arrays (pages 263–296): Chapter 9 Beamforming in Coupled?Oscillator Arrays (pages 297–320): Chapter 10 Overall Conclusions and Possible Future Directions (pages 321–323):
