Course Objectives
The objective of this course is to introduce to the students the basics of Theory of Electromagnetic Fields. This course represents a bridge between the courses on Electrical Circuits, which the student has already taken, and all the Electromagnetic Systems he/she will encounter in the 2nd Cycle. On successful completion of this module, the student should be able to describe, using proper mathematical models, wave propagation, wave sources, transmission lines, media properties and energy exchange
Course Content
- Fundamentals: Electromagnetic Field, Maxwell equations, Constitutive Equations, Boundary Conditions
- Time-varying Fields: Poynting and Unicity Theorems, Complex Vectors and Field polarization, Wave equation, Electrodynamical potentials
- Plane wave: Propagation vector, uniform and non-uniform plane wave, TE, TM and TEM waves, reflection and refraction of plane waves, under perpendicular or oblique incidence
- Transmission Lines: transmission line equations, wave impedance and characteristic impedance, forward and backward waves, reflection coefficient and VSWR, Smith diagram, impedance-matching circuits.
- Free-Space Radiation: Green Function, Vector Potentials, Radiation Condition, Equivalence and Reciprocity Principles, Fundamentals on Antennas
- Guided Waves: Fields in metallic or dielectric waveguides, Propagation Modes, Eigenvalues and Eigenvectors, Cutoff in a waveguide, Rectangular and Circular Waveguides
- Laboratory: Experiments and measurements on wave propagation in rectangular waveguide
Learning Outcomes (Dublin Descriptors)
On successful completion of this course, the student should
- have profound knowledge of fundamentals of Electromagnetic Fields
- have knowledge and understanding of the electromagnetic behavior of media and media interfaces and how time-varying fields and waves can be described
- be able to select the appropriate equations to describe the system under study
- understand and explain the characteristics of some basic system based on electromagnetic wave propagation (radio link, waveguide, optical fiber)
- demonstrate skill in analyzing engineering problems referring to electromagnetic waves; demonstrate capacity to read and understand text on Electromagnetics and on related topics
Prerequisites and Learning Activities
The student must know Calculus and Electrical Circuit Theory
