This book provides the analytical tools for the design, optimization, and physical construction of the electromagnetic media essential to modern communication systems. Intended for researchers, professionals, and students of electrical and telecommunications engineering, this work is also a valuable resource for those in computer science or engineering physics developing projects centered on the physical layer of electronic communication systems.

The fundamentals of electromagnetic fields and Maxwell's equations serve as the theoretical foundation of this book, establishing the principles of how waves propagate through various media. These interactions are modeled through Computational Electromagnetics (CEM), which the text introduces as an essential tool for approximating mathematical laws to the complexity of real-world electromagnetic phenomena. Building on this base, the first part explores the analytical design and physical construction of essential communication components, including antennas, waveguides, transmission lines, and printed circuit boards (PCBs). Together, these elements form the critical hardware backbone for modern digital networks, such as LTE, 5G, and 6G.

The second part of the book changes the focus from individual components to the analysis and design of complete electromagnetic communication links. The chapters included in this part provide the analytical framework for calculating radiated power, atmospheric attenuation, and free-space loss to ensure reliable signal quality in diverse real-world environments. By integrating the physical principles of antennas and transmission lines of previous part, the text details foundational propagation models, critical for predicting path loss in terrestrial point-to-point systems, satellite networks, and mobile radio channels.
