Electromagnetics and Transmission Lines

The book covers all the aspects of Electromagnetics and Transmission Lines for undergraduate course. The book provides comprehensive coverage of vector analysis Coulombs law electric field intensity flux and Gausss law conductors dielectrics capacitance Poissons and Laplaces equations magnetostatics electrodynamic fields Maxwells equations Poynting theorem transmission lines and uniform plane waves. The knowledge of vector analysis is the base of electromagnetic engineering. Hence book starts with the discussion of vector analysis. Then it introduces the basic concepts of electrostatics such as Coulombs law electric field intensity due to various charge distributions electric flux electric flux density Gausss law and divergence. The book continues to explain the concept of elementary work done conservative property electric potential and potential difference and the energy in the electrostatic fields. The detailed discussion of current density continuity equation boundary conditions and various types of capacitors is also included in the book. The book provides the discussion of Poissons and Laplaces equations and their use in variety of practical applications. The chapter on magnetostatics incorporates the explanation of Biot-Savarts law Amperes circuital law and its applications concept of curl scalar and vector magnetic potentials. The book also includes the concept of force on a moving charge force on differential current element and magnetic boundary conditions. The book covers all the details of Faradays laws time varying fields Maxwells equations and Poynting theorem. The book covers the transmission line parameters in detail along with reflection on a line reflection loss and reflection factor. The chapter on transmission line at radio frequency includes parameters of line at high frequency standing waves standing wave ratio and Smith chart. Finally the book provides the detailed study of uniform plane waves including their propagation in free space perfect dielectrics lossy dielectrics and good conductors. The book uses plain and lucid language to explain each topic. The book provides the logical method of explaining the various complicated topics and stepwise methods to make the understanding easy. Each chapter is well supported with necessary illustrations self explanatory diagrams and large number of solved problems. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
