Title : Wave Propagation in Communication
Course No : EE5505
Credits :
Objective:To provide a conceptual understanding of the basics of electromagnetism and its application to the principles of wave propagation for communication.
Learning Outcome:At the end of the course, the student will be able to

  • Understand the properties of electromagnetic (EM) waves
  • Analyze the propagation of plane EM waves in free space, media and at interfaces
  • Determine the characteristics of EM waves in bounded media
  • Apply the EM wave theory to transmission lines, antennas, guided wave and fiber-optic communication
