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.
This course aims to equip you with the ability to analyse static electric and magnetic field distributions for important electrical engineering situations (coaxial cables, transmission lines etc.), and to relate these to equivalent circuit parameters (resistance, capacitance, inductance). You will also gain an understanding of wave propagation and reflections on coaxial cables and other transmission lines. The propagation of electromagnetic plane waves will also be studied.The course also aims to equip you with an understanding of 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.• 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.
At the conclusion of this course you should be able to:• LO1: Analyse static electric and magnetic fields for electrical engineering applications (WA1, WA2)• LO2: Apply mathematics to describe, analyse and interpret the propagation of electromagnetic plane waves in different media (WA1, WA2)• LO3: Identify how atomic structure relates to the electrical properties of materials, and how atomic structure can be tailored to suit different applications. (WA1, WA2)• LO4: Gather and evaluate experimental data, interpret outcomes, draw reasoned conclusions, and communicate outcomes using written reports. (WA1, WA2, WA4, WA8, WA9)• LO5: Design, build and test a sensor based on the material properties of electronic components in a team environment, and report results as a device datasheet (WA3, WA4, WA8, WA9)

Artificial Intelligence Tools The use of Artificial Intelligence (AI) tools for each of the assessments in ENEL290 is summarised in the Table below. No AI use is allowed in the tests and exam because these are closed-book invigilated assessments. Students are always responsible for the accuracy of the submitted works, regardless of which tools are used.Assessment Item Permitted use of AI Laboratories - Generative AI tools are not restricted for this assessment. Laboratory Report - Generative AI Tools Are Permitted for Certain Parts of This Assessment Assignment - Generative AI Tools Are Permitted for Certain Parts of This Assessment Tests - Generative AI tools cannot be used for this assessment. Exam - Generative AI tools cannot be used for this assessment.Generative AI Tools Are Permitted for Certain Parts of This AssessmentIn these assessments (Lab Report, Assignment), you are permitted to use generative artificial intelligence (AI) for the purpose of proof reading and editing the document, and for gathering and summarising knowledge. No other use of generative AI is permitted. To assist with maintaining academic integrity, you must appropriately acknowledge any use of generative AI in your work. Please include a Statement of AI use (if no AI tool has been used, then this must also be stated) and a listing of all prompts provided to the AI tool, clearly indicating which AI tools were used and how they contributed to your assessment.
The examiners will award a failing grade to students who score less than 40% for the Tests and Exam combined. More formally, (Test1Percent * 0.2 + Test2Percent * 0.2 + ExamPercent * 0.2) / 0.6 must be greater than or equal to 40 for a pass mark to be awarded. This note is put in place to ensure that each student has adequately shown to the examiners they have gained some mastery of the topic.Labs (20%)Students are required to complete all 3 labs (2% each) and submit 1 formal Lab Report (14%). Students will be allocated to each of the labs. The labs will run concurrently for 5 weeks with 1-2 TAs per lab (except Lab C which will run for 4 weeks only). Labs will be marked by TA/lecturers at end of each session.A. Transmission line reflections (Electronics Lab)B. Diodes (Electronics Lab)C. Statics & breakdown (High Voltage Lab) Scaling of marksIn order to maintain consistency across courses and fairness for students, scaling of raw marks occurs. In the Faculty of Engineering, target course GPAs are calculated based on the performance of the cohort of students in their courses in the previous year. Scaling of the raw total course marks is normally performed so that when converted to grades (using UC Grade Scale) the outgoing GPA is in line with the target GPA for a course. Scaling up or down can occur.The Grading Scale for the University:https://www.canterbury.ac.nz/study/study-support-info/study-related-topics/grading-scale
Lateness Penalties For the Lab Report and Assignment, a lateness penalty of 10% (in absolute terms) per day or part day late will be deducted from the original mark. For example, an assignment with a nominal mark of 83% submitted 0-24 hours late will receive a mark of 73%, and submitted 24-48 hours late will receive 63%.
