Description

Waves in electrical engineering. Static electric and magnetic fields. Transmission lines: equivalent circuit, wave propagation, reflections and matching. Plane waves: time varying fields and Maxwell’s Equations. Electrical engineering materials: conductors, insulators and semiconductors.

Topics covered include:

• Electrostatics and Magnetostatics: Electric and Magnetic Fields; Gauss’ Law, Coulomb’s Law, Ampere’s Law; Capacitance and inductance; Coaxial cables.
• Transmission Lines: Wave equations; Characteristic impedance; Reflections and impedance matching; Lossy and lossless transmission lines; Standing waves and Voltage Standing Wave Ratio; Smith Charts; Examples: coaxial cables, microstrip lines.
• Plane Waves and Time Varying Fields: Maxwell’s Equations in free space and source-free media; Conduction Current; Charge Dissipation; Wave equation and plane-wave solutions; Complex permittivity; Intrinsic impedance; Skin depth.
• Physical & Electronic Structure of Materials: Isolated atoms; Atomic bonding; Crystallography; Crystalline defects; Thermal expansion.
• Conductors: Conduction mechanisms; Temperature dependence; Skin effect; Thin metal films; Interconnects; Thermal conductivity; Thermal noise .
• Dielectrics/Insulators: Polarisation; Relative permittivity; Dielectric strength; Insulator breakdown; Capacitor dielectric materials.
• Semiconductors: Intrinsic semiconductors; Extrinsic semiconductors; Temperature dependence; Recombination; Majority & minority carriers; Optical absorption; Basic diode operation principles; Basic transistor operation principles.

Learning Outcomes

At the end of this course, students will be able to:
1. Analyze static electric and magnetic field distributions for important electrical engineering situations (coaxial cables, transmission lines etc.)
2. Relate these to equivalent circuit parameters (resistance, capacitance, inductance)
3. Develop understanding of wave propagation and reflections on coaxial cables and other transmission lines
4. Understand the propagation of electromagnetic plane waves
5. Understand the electrical properties of materials, including: conduction mechanisms, dielectric properties and breakdown phenomena, basic crystallography, bonding and band structure in conductors, insulators and semiconductors; doping, impurities, electrons and holes in semiconductors; basic diode operation principles
