Waveguides and antennas - 4AMSC410

Goal(s)

This course provides in depth coverage of all aspects electromagnetics, with a focus on field and wave generation and propagation. The course will focus on the more practical aspects of E-M theory, with application examples. The specific subjects covered will be Maxwell’s equations, electromagnetic wave propagation, transmission lines, waveguides and antennas.
Students completing this course should be able to :

• understand Maxwell’s equations and solve them for specific regular geometries
  *understand general electromagnetic wave propagation
• work out simplified solutions to waveguides example problems in regular geometries.
• understand antennas theory and both electrical and radiation characteristics
