Catalog Description
Electromagnetic Field Theory acquire understanding and ability to analyze static electric and magnetic fields, timevarying 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, timevarying electric and magnetic fields the course covers basics of antenna theory and introductory concepts on application numerical techniques have also been discussed.
