Delivering the best possible solution for phase noise and output power efficiency in oscillatorsThis complete and thorough analysis of microwave oscillators investigates all aspects of design, with particular emphasis on operating conditions, choice of resonators and transistors, phase noise, and output power. It covers both bipolar transistors and FETs. Following the authors' guidance, readers learn how to design microwave oscillators and VCOs that can be tuned over a very wide frequency range, yet have good phase noise, are low cost, and are small in size. All the essential topics in oscillator design and development are covered, including:* Device and resonator technology* Study of noise sources* Analysis methods* Design, calculation, and optimization methodologies* Practical design of single and coupled oscillatorsWhile most of the current literature in the field concentrates on classic design strategies based on measurements, simulation, and optimization of output power and phase noise, this text offers a unique approach that focuses on the complete understanding of the design process. The material demonstrates important design rules starting with the selection of best oscillator topology, choice of transistors, and complete phase noise analysis that leads to optimum performance of all relevant oscillator features. Also included are CMOS oscillators, which recently have become important in cellular applications. For readers interested in specialized applications and topics, a full chapter provides all the necessary references.The contents of the text fall into two major categories:* Chapters 1 through 9 deal with a very detailed and expanded single resonator oscillator, including a thorough treatment of both nonlinear analysis and phase noise* Chapters 10 and 11 use the knowledge obtained and apply it to multiple coupled oscillators (synchronized oscillators)This text is partially based on research sponsored by the Defense Advanced Research Projects Agency (DARPA) and the United States Army and conducted by Synergy Microwave Corporation. With the wealth of information provided for the analysis and practical design of single and synchronized low-noise microwave oscillators, it is recommended reading for all RF microwave engineers. In addition, the text's comprehensive, step-by-step approach makes it an excellent graduate-level textbook.

This is a comprehensive and accessible textbook designed for senior undergraduate students, graduate students, and practicing engineers working in high‑frequency, microwave, and wireless communication fields. Blending classical theory with modern applications, this book provides a clear and intuitive understanding of electromagnetic phenomena essential for today’s high‑frequency engineer.The subject of electromagnetic waves lies at the heart of contemporary technologies—ranging from wireless communication and radar systems to optical fibers and metamaterials. This book presents the material with a strong emphasis on conceptual clarity and analytical thinking, enabling readers to move confidently from fundamental principles to real‑world applications.The text begins with transmission line theory, highlighting the limitations of conventional circuit approaches at radio frequencies and introducing the essential concept of distributed elements. Key topics such as wave equations, reflections, impedance matching, and practical transmission‑line applications are developed in a systematic and intuitive manner. The formulation of Maxwell’s equations—derived rigorously in both integral and differential forms—forms the theoretical backbone of the book, along with an in‑depth discussion of boundary conditions.Subsequent chapters explore uniform plane waves, polarization, wave propagation in conducting media, and phenomena such as skin depth and surface currents. Wave behavior at media interfaces, including total internal reflection, is treated in detail. Dedicated chapters on metallic and dielectric waveguides introduce modal propagation with applications to microwave systems and optical technologies such as thin‑film devices and optical fibers.Antenna theory is developed from fundamental radiators to antenna arrays, leading to a powerful Fourier transform relationship between current distribution and radiation patterns. Propagation of electromagnetic waves in radio communication environments—including the ionosphere—is discussed with insight into ionized and magnetized media. Modern topics such as metamaterials, computational electromagnetic methods (FDM, FDTD, MoM), and emerging applications round out the text.Each chapter includes carefully designed solved and unsolved problems, along with conceptual review questions that emphasize physical understanding rather than algebraic complexity. An extensive mathematical appendix supports the main text and makes the book self‑contained.Written with clarity and pedagogy in mind, this book aims to make the study of electromagnetic waves both rigorous and enjoyable—serving as a reliable guide for students and a valuable reference for practicing engineers.
