《天線手冊（第 22版）》是美國業餘無線電協會經典手冊之一，包含了設計完整的天線系統所需的所有信息。本書中既有現代天線理論，也含有大量實用的天線設計與製作的實例。通過使用本書，讀者不僅可以獲得基本的天線設計知識，如線天線、環形天線、垂直極化天線、八木天線等，並且以這些知識為基礎，還可以進一步瞭解高等天線的理論和應用。本書譯自英文原版第 22版，該版經過廣泛修訂，在原來版本的基礎上補充了大量的信息，全新改寫了“建造天線系統和鐵塔”“地面效應”“移動甚高頻和超高頻天線”“移動和海事高頻天線”等章節，並提供了很多令人興奮的新天線項目，如C型極子不受地面影響的高頻天線，在微波應用中的貼片天線和Vivaldi天線，用於八木天線的一組新的半構件設計等。 本書適合業餘無線電愛好者，天線技術和射頻技術等相關專業的工程師、技術人員及大專院校師生閱讀，本書的內容將為他們的學習與實踐提供非常有益的幫助。

The investigation of wave propagation in non-uniform transmission lines is common to many engineering situations. This book presents and develops the mathematical tools required to effectively exa

Essentials of Electromagnetics for Engineering, first published in 2000, provides a clearly written introduction to the key physical and engineering principles of electromagnetics. Throughout the book, the author describes the intermediate steps in mathematical derivations that many other textbooks leave out. The author begins by examining Coulomb's law and simple electrostatics, covering in depth the concepts of fields and potentials. He then progresses to magnetostatics and Maxwell's equations. This approach leads naturally to a discussion of electrodynamics and the treatment of wave propagation, waveguides, transmission lines, and antennas. At each stage, the author stresses the physical principles underlying the mathematical results. Many homework exercises are provided, including several in Matlab and Mathematica formats. The book contains a separate chapter on numerical methods in electromagnetics, and a broad range of worked examples to illustrate important concepts. It is suita
