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 )
