The Department of Electrical and Electronics Engineering, KCG College of Technology organized a guest lecture on the Electromagnetic Theory course on 7.9.2017 for the second year students. Dr.R. AZHAGUMURUGAN, Associate Professor, Department of EEE, Sri Sai Ram Engineering College was the resource person. Dr. P. S. Mayurappriyan introduced about the speaker to the audience.
He started the lecture asking the students about the sources of electromagnetic fields. Students actively responded to the questions asked by him. He explained about the five units of the course. Starting with the first Unit, he explained about sources and effects of electromagnetic fields, Coulomb’s Law, Gauss’s law and its applications. In Unit II, he explained about the electric field and equipotential plots, uniform and non-uniform fields, utilization factor – electric field in free space, conductors, dielectric polarization, dielectric strength – electric field in multiple dielectrics , Boundary conditions, Poisson’s and Laplace’s equations, applications. He gave an overview of Lorentz force, Biot–Savart’s Law, Ampere’s Circuit Law, infinite sheet of current, magnetic flux density (B) – B in free space, conductor, magnetic materials – magnetization, Poisson’s equation. He also highlighted the significance Faraday’s law, Maxwell’s equation (differential and integral form) from Unit IV. He also illustrated about electromagnetic wave generation and equations – wave parameters; velocity, intrinsic impedance, propagation constant, conductors- skin depth – Poynting vector – plane wave reflection and refraction – standing wave – Applications.
Finally he gave some tips to study all the five units of this course effectively.
The lecture was over at 12 noon.
