Description

Waves in electrical engineering. Static electric and magnetic fields. Transmission lines: equivalent circuit, wave propagation, reflections and matching. Plane waves, antenna basics and electromagnetic interference. Electrical engineering materials: conductors, insulators and semiconductors.

The curriculum for this course includes:

1. Electrostatics and Magnetostatics: Review of Gauss’s Law and Ampere’s Law; Capacitance and Inductance; Electric and Magnetic Fields; Capacitance and Inductance for common EEE situations: Coaxial cables (e.g. TV antenna feed cables), Twin-wire cables (e.g. twisted pair), Wires above ground planes (e.g. PCB traces, power transmission lines)

2. Transmission Lines: General wave equation and wave propagation properties; Circuit equations for transmission lines with distributed capacitance/inductance; Signal and wave propagation along transmission lines; Reflections at discontinuities and impedance matching; Lossy versus lossless transmission lines; Dispersion

3. Plane Waves and Related Topics: Maxwell’s Equations in free space and source-free media; Wave equation and plane-wave solutions; Attenuation, reflection and impedance matching; Polarisation; Contemporary topics and applications; Introduction to antennas and concepts in electromagnetic interference (EMI)

4. Physical & Electronic Structure of Materials: Isolated atoms; Atomic bonding; Crystallography; Crystalline defects; Thermal expansion

5. Conductors: Conduction mechanisms; Temperature dependence; Skin effect; Thin metal films; Interconnects; Thermal conductivity; Thermal noise

6. Dielectrics/Insulators: Polarisation; Relative permittivity; Dielectric strength; Insulator breakdown; Capacitor dielectric materials

7. Semiconductors: Intrinsic semiconductors; Extrinsic semiconductors; Temperature dependence; Recombination; Majority & minority carriers; Optical absorption; Basic diode operation principles; Basic transistor operation principles

Learning Outcomes

  • Able to analyze static electric and magnetic field distributions for important electrical engineering situations (coaxial cables, transmission lines etc.),
