The text explains the physical and mathematical aspects of the highly complicated electromagnetic theory in a very simple manner. The book begins with a introductory chapter on vector theory and then moves on to explain the effectiveness of Ampere s circuital law and Biot-Savart s law in dealing with magnetostatic problems, derivation of Maxwell s field equations from the fundamental laws of Faraday and Ampere, free-space solutions of wave equations, and the theory of skin effect. Finally, it concludes with the applications of Smith chart in solving transmission line problems and the theory of rectangular and circular waveguides
