Last modified by Leon Luo on 2023/01/06 13:50


Electromagnetism is a key concept in electrical and computer engineering, as it is essential for understanding how electric and mechanical energy can be converted, transmitted, and utilized. This course will introduce students to the principles of electromagnetism. Learning the first principles will greatly assist students in understanding how electromagnetism can be applied in various fields, including communication systems, RF/microwave devices, optical fiber systems, antennas, remote sensing, and radio astronomy. The course will cover the fundamentals of electromagnetic theory, including electrostatics, magnetostatics, and the relationship between electric and magnetic fields, as well as the Maxwell equations. Students will also learn about the behavior of waves and how they propagate through various materials and devices. The course will focus on the practical applications of electromagnetism, including the design and analysis of low-frequency systems and high-frequency systems. Some of the specific topics that will be covered include capacitors, inductors, transformers, electromagnetic forces, power losses in electromagnetic systems, transmission lines, impedance matching circuits, and waveguides. This course is intended for students who have already completed undergraduate physics (PHYS1231 - Higher Physics 1B) and vector calculus courses ( MATH2069 - Mathematics 2A ), as well as having a basic understanding of circuit theory techniques. The intended goal of this course by the lecturers is to provide students with a strong foundation in electromagnetism and how it is applied in engineering applications such as energy systems, telecommunications, and computing. By the end of the course, students should be able to understand and analyze various electromagnetic devices and systems and be able to apply this knowledge to the design and implementation of electrical power systems and modern wireless communications systems.


These concepts are studied through course content, mainly lecture notes and course recommended textbooks. Please note, unless referenced from another source, please assume the following information presented is interpreted, studied, and re-expressed from the course content. Furthermore, please refer to the course content directly, e.g. ask the lecturer or read the textbook, for the most relevant knowledge required for the course.

Low-frequency Systems


The fundamental principle behind electrostatics is the electric field. It is a field that manifests the force experienced by a unit charge, however in electrostatics, it is by a stationary unit charge. The field's unit is defined by Newtons per Coloumbs (N/C) or Voltage per Metre (V/m).
