The book Microwave Engineering by David M. Pozar is considered a fundamental reference in the field of microwave engineering. It is aimed primarily at advanced students of electrical engineering and telecommunications, as well as professionals in RF and microwave system design. Its purpose is to provide a solid understanding of the principles and applications of microwaves in modern systems, from waveguides to antennas to active circuits.
This review is organized with the following table of contents:
1. Editions and Evolution
Since its first edition, published in the 1980s, Microwave Engineering has evolved significantly to remain a relevant text in the field:
- First edition: Introduced the fundamentals of microwaves, transmission lines and S-parameters, laying the groundwork for future developments.
- Second edition: More detailed chapters were added on active circuits, such as amplifiers and oscillators, reflecting the advancement of technology at the time.
- Third edition: Incorporated topics related to antennas, more depth in passive systems and more practical examples.
- Fourth edition: Integrates improvements in circuit and component design, as well as new practical applications and a reorganization of some chapters to improve learning flow. However, it does not include more recent developments such as 5G or artificial intelligence-assisted design techniques.
The evolution of the book has been consistent with the needs of industry and academia, although a fifth edition addressing emerging technologies would be welcome.
2. Summary of Content
The book is organized into chapters that address key topics in microwave engineering:
- Fundamentals of electromagnetic wave propagation.
- Transmission lines and waveguides.
- S-parameter network and network theory.
- Passive components, such as couplers and power dividers.
- Design and analysis of active circuits, including amplifiers and oscillators.
- Introduction to antennas and radiation techniques.
- Microwave systems analysis methods.
The book’s approach combines a solid theoretical basis with practical examples and real applications, making extensive use of mathematical equations, graphs and illustrative diagrams.
3. Critical Analysis
3.1 Clarity and Accessibility
The technical language used is clear and suitable for an audience with advanced knowledge in electromagnetics. However, it can be dense for beginners in the subject. The explanation of key concepts, such as S-parameters or Smith diagrams, is well structured and accompanied by numerical examples that facilitate understanding.
3.2 Topic Coverage
Pozar achieves comprehensive coverage of the microwave field, from theoretical fundamentals to practical applications. The book balances theoretical and practical aspects nicely, making it a valuable resource for both academia and industry.
3.3 Present Status
Although the latest edition is from 2011, the fundamental principles it addresses are timeless. However, the book could benefit from an update to include recent advances in microwave technologies, such as 5G systems, advanced MMIC devices, and artificial intelligence-aided design techniques.
3.4 Accuracy
The content is highly accurate, with rigorous explanations supported by detailed calculations and references to relevant research. No significant errors are expected to be found in the formulas or data provided.
3.5 Practical Application
The book is notable for its practical examples, problems at the end of each chapter and proposed solutions. This makes it useful for the design of real components and systems in research and development environments.
3.6 Design and Format
The design is functional but not particularly attractive. Diagrams and graphics are clear and serve their purpose, although the overall format could be modernized to improve the reading experience, especially in digital editions.
3.7 Summary
Positive Features:
- Comprehensive coverage of the subject with a balanced approach between theory and practice.
- Numerical examples and well-designed problems that reinforce learning.
- Technical accuracy and mathematical rigor.
Negative Features:
- It does not include recent developments in microwave technologies.
- It can be challenging for readers without a solid background in electromagnetics.
- The visual design of the text could be improved to make it easier to read.
4. Problems and Solutions
Each chapter of the book includes a series of problems designed to reinforce the concepts explained and provide practical experience in the analysis and design of microwave systems. The problems range from basic wave propagation calculations to complex active and passive system designs.
Problem Features:
- Level of difficulty: Ranging from basic conceptual problems to advanced calculations and design analysis.
- Thematic coverage: The problems are aligned with the contents of each chapter, facilitating the direct application of the concepts learned.
- Practical approach: Many of the problems focus on real applications, such as filter design, antenna analysis and system simulations.
Wiley, the publisher, offers a detailed solutions manual for instructors. This manual is available only to registered teachers who use the book in official courses. A pdf file with the solved problems is also available online.
5. Comparison
Compared to other microwave engineering texts, such as Foundations of Microwave Engineering by R. E. Collin, Pozar’s book is more accessible and practical for students and designers. However, for a more modern approach, other resources that address technologies such as 5G might be more suitable.
If looking for something functional, but simpler, it is recommended to start with easier texts such as RF Circuit Design by Bowick.
6. Conclusion
Microwave Engineering by David M. Pozar remains an indispensable reference work in the microwave field, ideal for advanced students and professionals seeking a solid understanding of the fundamentals and applications of the subject. Although it could benefit from an update, its technical rigor and clarity of explanation make it a valuable resource.
This book is highly recommended for advanced university courses, RF and microwave system designers, and telecommunications professionals. Less suitable for beginners with no prior knowledge of electromagnetics and mathematics.
