In this section, we will briefly summarize the main topics covered in each chapter of the book.
Chapter 1 introduces the basic concepts and terminology of microwave engineering, such as frequency bands, wavelength, power, attenuation, decibel, scattering parameters, Smith chart and transmission matrix.
Chapter 2 discusses the theory and applications of microwave transmission lines, such as coaxial lines, parallel-plate lines, striplines and microstrip lines. The chapter also explains the concepts of reflection coefficient, standing wave ratio, impedance transformation and input impedance.
Chapter 3 deals with the theory and applications of waveguides, such as rectangular waveguides, circular waveguides and dielectric waveguides. The chapter also describes the modes of propagation, cutoff frequency, phase velocity, group velocity and dispersion in waveguides.
Chapter 4 covers the theory and applications of resonators, such as cavity resonators, dielectric resonators and microstrip resonators. The chapter also defines the concepts of quality factor, bandwidth, loaded and unloaded Q, coupling coefficient and insertion loss.
Chapter 5 explains the methods and techniques of impedance matching and tuning in microwave circuits, such as stub matching, quarter-wave transformer matching, single-stub tuner, double-stub tuner and Smith chart matching.
Chapter 6 presents the principles and methods of microwave network analysis, such as ABCD parameters, Z parameters, Y parameters, S parameters and T parameters. The chapter also shows how to use these parameters to analyze various microwave networks and devices.
Chapter 7 describes the characteristics and applications of passive microwave components, such as directional couplers, power dividers, hybrids, circulators, isolators and attenuators. The chapter also discusses the design and performance of these components using S parameters and transmission matrix.
Chapter 8 focuses on the theory and design of microwave filters, such as low-pass filters, high-pass filters, band-pass filters and band-stop filters. The chapter also introduces the concepts of filter specifications, filter synthesis, filter realization and filter implementation.
Chapter 9 explains the properties and applications of ferrite devices in microwave circuits, such as gyrators, phase shifters, modulators and switches. The chapter also describes the phenomena of ferromagnetism, ferrimagnetism and gyromagnetism in ferrite materials.
Chapter 10 covers the operation and characteristics of active microwave devices, such as diodes (PIN diode, varactor diode, 0efd9a6b88
