Course Objectives
- Students will familiar with Maxwell's equations, Transmission Line Theory, Electromagnetic Waves, Radio Wave propagation etc. It will be helpful to EC/EI students while designing a system on EMI/EMC point of view.
- It will help to build the concepts on electromagnetic theory.
- It will help to build the fundamental concepts so that the students can design waveguide, transmission lines, etc. by their own.
- It will help to introduce the concepts on applications of electromagnetic theory in research and higher studies.
