Designed as a textbook for the students of electronics and communi-cation engineering, and electrical and electronics engineering, it covers the subject of electromagnetism with a clear exposition of the theory in association with the practical applications. 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 Amperea€™s circuital law and Biot-Savarta€™s law in dealing with magnetostatic problems, derivation of Maxwella€™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. Key Features in Large number of solved examples and chapter-end problems in Appendices to give the solutions of wave equations in waveguides in Three-dimensional figures to illustrate theories in Generalized solution of Maxwella€™s equations Besides undergraduate students of engineering, it would be useful for the postgraduate students of physics.E2. 15. Since the wires carry opposite currents, the charges in the wires are also opposite in nature. -Q Fig. E2.15 Let x be a distance to a point P from the wire A, as shown in the figure.
