Students will be 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 from EMI/EMC point of view.

It will help to build the concepts of electromagnetic theory.

It will help to build the fundamental concepts so that the students can design waveguide, transmission lines, etc. on their own.

It will help to introduce the concepts on applications of electromagnetic theory in research and higher studies.

After the completion of this course, students will be able to:

CO1: understand the fundamentals and concepts of electromagnetic theory
CO2: describe the various aspects of electromagnetic theory.
CO3: analyze the different components like a waveguide, transmission lines, etc.
CO4: apply the knowledge to investigate the cause and effect qualitatively
CO5: construct/design some basic designs on their own
