Course Outline and Policy

Description

This course is intended to be a broad introduction to Engineering Electromagnetics and its applications. The topics include fundamental laws and axioms for Electrostatics and Magnetostatics, Time-Varying Fields, and Maxwell’s Equations. Subsequently, the axioms is utilized to describe plane electromagnetic waves and its mathematical model for different media and its interaction with interfering planes. In addition, concepts related to Transmission Line Theory is also introduced.

Postconditions On the completion of this course the students will be able to:
1. Express and Elaborate Maxwell's Equations in differential and integral forms and the constitutive relations between the flux densities and field intensities of the electrostatics, magnetostatics and electrodynamic fields.
2. Derive the Helmholtz wave equations in its various forms and the wave nature of their solutions for time-harmonic waves in various mediums.
3. Apply fundamental electromagnetic concepts in applications such as Transmission Lines and Antennas.
4. Use MATLAB to solve simple EM problems in the domains of RF circuits and Antennas.
