|Pre-requisites//Exposure||Engineering Physics– I|
The students will learn and understand
- Behaviour of electrostatic and electromagnetic fields and their application in electrical and electronics engineering fields.
- Maxwell’s equation in integral and differential form, their interpretation and applications.
- Propagation of EM wave in free space, conductors & dielectrics.
On completion of this course, the students will be able to
- Calculate electric and magnetic fields from stationary and dynamic charge and current distributions
- Gain knowledge of static and time varying fields.
- Define electric and magnetic fields and solve simple electrostatic boundary problems
- Understand the phenomenon of wave propagation with the aid of Maxwell’s equations.
Electromagnetic Field Theory acquire understanding and ability to analyze static electric and magnetic fields, time-varying electric and magnetic fields, wave propagation in different types of media. This course may also be useful for the practicing engineers who want to refresh their understanding in Electromagnetics. Along with static electric and magnetic fields, time-varying electric and magnetic fields the course covers basics of antenna theory and introductory concepts on application numerical techniques have also been discussed.
