Fundamentals of Electromagnetic Theory for Chipless RFID
摘要
This chapter introduces the fundamental principles of electromagnetic (EM) theory, serving as essential tools for understanding chipless RFID systems and as valuable resources to support the concepts discussed throughout the Chipless RFID handbook. Key topics covered include EM wave propagation, EM energy and power, the Friis equation, the backscattering principle, and the resonance phenomenon. These foundational concepts provide the necessary framework for exploring the design and functionality of chipless RFID systems in subsequent chapters.
