EEEN30030 Electromagnetic Waves

Academic Year 2022/2023

This module aims to develop an understanding of electromagnetic waves with emphasis on :(i) the vector calculus of electromagnetic theory, (ii) the physical basis and predictions of this theory, and (ii) engineering application and implications of the results. The module is intermediate or advanced level.Topics include:- Maxwell's Equations (physical basis and vector calculus formalism);- Electromagnetic waves in media and at boundaries;- Electromagnetic analysis and design of waveguiding structures;- Electromagnetic analysis of devices and components operating over a wide range of frequencies, optical, microwave and radiowave. NOTE: RE-SIT EXAMINATIONS will normally take the form of a writen examination of the same form and standard as the standard (first sitting of the) examination paper.

Learning Outcomes:

SUMMARY: On the successful completion of this module students should be able to:- Physically explain and derive the fundamental equations governing electromagnetic fields and waves- Apply the fundamental equations (for different physical situations, i.e. materials and frequencies) to derive solutions and then interpret the physical and engineering implications of these results; - Design electromagnetic components to meet given specifications and compare the performance of alternative implementations or approaches;- Communicate the results of their work in both written and oral form.

IN DETAIL : LO (1) LEARNING OUTCOME: Physically explain the fundamental equations governing electromagnetic fields and waves: SOME OF THE TOPICS ADDRESSED: (Faradays? and Amperes? laws, E, D, H, B vector fields and Poynting vector, etc.). LO (2) Derive the fundamental equations governing electromagnetic fields and waves by applying vector calculus: (Gradient, divergence, curl, Greens? and Stokes? theorems etc.). LO (3) Apply the fundamental equations to examine different materials (insulators, lossy dielectrics, conductors). LO (4) Apply the fundamental equations to different physical situations: Different frequency regimes: (Optical, microwave, radio wave, AC power lines, electrostatics). LO (5) Derive solutions and then interpret the physical implications of these results: (Transverse electromagnetic wave ? polarization, velocity). LO (6) The physical engineering implications of the solutions derived: (Losses in media, impedence matching, back reflections, phase and group velocity, dispersion). LO (7) Design electromagnetic components to meet given specifications: (Including technical, cost, legal and environmental impact requirements) (Examples of components: anti-reflection coatings, waveguides (optical fiber, metallic and micro-strip), antennas). LO (8) Compare the performance of alternative implementations or approaches:( Including technical, cost, legal and environmental impact requirements) (Performance of : communication channels and numerical solutions of equations). LO (9) Communicate the results of their work in writing:(Written mid-term and final examinations and essay) (Essays involve issues of professionalism and plagiarism; Topics covered include technical, cost and environmental impact issues ). LO (10) Communicate the results of their work in oral form: (Oral presentation and discussions during tutorials and lectures)(Oral presentations involve issues of professionalism and plagiarism; - Topics covered include technical, cost and environmental impact )

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
• Online automated feedback

How will my Feedback be Delivered?

Students are strongly encouraged to attend lectures. A sign-up sheet is taken and poor attenders identified and approached. Students are encouraged to form study groups to provide peer review and assessment. Before submission of essay student can discuss the processed topic and layout with the lecturer. Students can discuss their attempted solutions of exercises in the notes with the lecturer (opportunities at ends of lectures provided) Post-midterm the examination material solutions will be discussed in class. Student can privately ask for feedback. Feed back on essay and video marks provided on request by students.
