ECE 5105 Electromagnetic Waves (3C)
Maxwell's electromagnetic field theory and its applications to engineering problems. 5105: Fundamental concepts and theorems; elementary wave theory and boundary value problems; applications to radiation, transmission line and waveguide problems. 5106: Analytical techniques (Green's theory, modal analysis, etc.) pertaining to guided wave propagation and to scattering and diffraction by discontinuities and inhomogeneties in metallic and dielectric waveguiding structures.
The design of microwave and optical components, such as antennas, waveguides, etc., as well as the effective exploitation of diverse types of communication channels, is based upon the theory of electromagnetic fields, expressed most efficiently by Maxwell’s equations. However, the solution of these equations requires an in-depth understanding of a number of diverse techniques.
Typically offered: Fall. Program Area: Electromagnetics.
Prerequisites: Graduate standing and 3106.
Engineering: Proficiency in undergraduate electromagnetic fields. (Knowledge of the material covered in ECE 3106 is mandatory). Mathematics: Differential equations and Fourier concepts. Also Graduate standing.
Department Syllabus Information:Major Measurable Learning Objectives:
- Demonstrate facility in using Maxwell’s equations to evaluate basic plane wave propagation, interaction with planar surfaces, and energy storage
- Describe the fundamental principles of propagation, particularly with regard to the interaction with obstacles
- Describe the effects of a layered medium on the reflection of a plane wave
- Decompose an arbitrarily polarized incident wave into its perpendicular and parallel vector components and determine the total fields above and beneath a planar interface
