Electromagnetic Field Theory

The comprehensive study of electric magnetic and combined fields is nothing but electromagnetic engineering. Along with electronics electromagnetics plays an important role in other branches. The book is structured to cover the key aspects of the course Electromagnetic Field Theory for undergraduate students. 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 Coulomb's law electric field intensity due to various charge distributions electric flux electric flux density Gauss's law divergence and divergence theorem. 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 Poisson's and Laplace's equations and their use in variety of practical applications. The chapter on magnetostatics incorporates the explanation of Biot-Savart's law Ampere's circuital law and its applications concept of curl Stoke's theorem 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 Faraday's laws time varying fields Maxwell's equations and Poynting theorem. 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 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. The variety of solved examples is the feature of this book which helps to inculcate the knowledge of the electromagnetics in the students. Each chapter is well supported with necessary illustrations and self-explanatory diagrams. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
