Applied Electromagnetics For Engineers

About the course

Applied electromagnetics for engineers is designed to be an application oriented course while covering all the theoretical concepts of modern electromagnetics. It begins by an in-depth study of transmission lines which play an important role in high-speed digital design and signal integrity of PCBs. After a brief review of necessary mathematics (coordinate systems, vector analysis, and vector fields), the course covers analytical and numerical solution of Laplace's and Poisson's equations, quasi-static analysis of capacitors and skin effect, inductance calculations, and Maxwell equations. Wave propagation in free-space, ferrites, and peroidic media are covered along with waveguides (rectangular, planar dielectric, and optical fibers) and antennas. The course includes a balance between theory, programming, and applications. Several case studies will be discussed.

Intended Audience
UG 2nd, 3rd Year

Prerequisites
Electricity and magnetism at the level of high-school, Vector analysis, Differential and integral calculus, programming using Matlab (preferable)

Course instructor




Dr. Pradeep Kumar K. obtained his PhD from IIT Madras specializing in quantum cryptography. He joined the Department of Electrical Engineering
at IIT Kanpur in 2009. He is also associated with the Centre for Lasers & Photonics. At IIT Kanpur he and his students work in the fields of 
quantum
key distribution, nonlinear fiber optics for signal processing, mitigation of linear and nonlinear impairments in coherent optical
communications,
mode locked fiber lasers and chaos, fiber-optic sensors for undersea applications, and fiber-optic modeling. He is also actively
involved in
the LIGO-India effort under IndiGO umbrella.
His lab develops single-photon detectors, single- and subcarrier RF transceivers, and is
currently working on true random number generators. He has published over 40 papers in peer reviewed journals and conferences. He also holds
three
patents (one granted and two pending). His MOOC courses on NPTEL has been very popular with more than 15000 enrollments from across
the country.
