HANDOUT ON ELECTRO MAGNETIC FIELD THOERY Class & Sem. : II B.Tech – I Semester Year Branch Credits : 3 : ECE : 2017-2018 ============================================================================ 1. Brief History and Scope of the Subject Electromagnetics (EM) may be regarded as the study of the interactions between electric charges at rest and in motion. It entails the analysis, synthesis, physical interpretation, and application of electric and magnetic fields. EM principles find applications in various allied disciplines such as microwaves, antennas, electric machines, satellite communications, bioelectromagnetics, plasmas, nuclear research, fiber optics, electromagnetic interference and compatibility, electromechanical energy conversion, radar meteorology," and remote sensing. In physical medicine, for example, EM power, either in the form of short waves or microwaves, is used to heat deep tissues and to stimulate certain physiological responses in order to relieve certain pathological conditions. EM fields are used in induction heaters for melting, forging, annealing, surface hardening, and soldering operations. Dielectric heating equipment uses shortwaves to join or seal thin sheets of plastic materials. EM energy offers many new and exciting possibilities in agriculture. It is used, for example, to change vegetable taste by reducing acidity. EM devices include transformers, electric relays, radio/TV, telephone, electric motors, transmission lines, waveguides, antennas, optical fibers, radars, and lasers. The design of these devices requires thorough knowledge of the laws and principles of EM. 1. Pre-Requisites ➢ Vector analysis. ➢ Coordinate systems. 2. Course Objectives: • To introduce the concepts of Electrostatics and Magnetostatics. • To develop an understanding of Electromagnetic Waves and their Propagation. 3.
