Working through these problems diligently will help your overall grade in the course because these problems and similar ones will appear on the tests. Exam Policy There will be (3) in-class Exams (2 midterms and 1 final). For each exam, textbooks, notes, and phones/tablets are not allowed. one hand-written double-sided equation sheet on 8.5x11” paper and a calculator are allowed. If an Exam is missed without a certified medical excuse or prior instructor approval, you will receive a zero. Certified excuses and prior approval will be dealt with individually. A single makeup exam for will be offered, held at a designated time at the end of the semester. This makeup Midterm Exam will include the contents assessed by all three exams, regardless of which exam is being "made up". To request an excused absence, 1) write a formal hard copy letter to me, dated and signed, stating your specific request and the reason you are asking for an excused absence; 2) provide documentation supporting your request; 3) bring this letter and the documentation to me in person before the requested date (if an absence is foreseeable) or within one day after the absence (if it is of unforeseeable nature), at which time we will discuss your request. Special cases will be dealt individually. Grade Disputes Students may request a regrade on test problems. However, verbal requests for regrades will not be considered. A written regrade request must be submitted to the instructor within one week of the exam being returned to the class. The student should email the instructor a document that contains the a copy of the worked problem that’s being disputed and a written argument that make a case as to why the grade should be changed. Do NOT mark on the original assignment. Oral Presentations Policy Near the end of the course, all students will be asked to create a short (5 min) oral presentation about a suitable electromagnetics topic of their choice. For example, one of the Technical Briefs in our textbook, or another device, effect, or idea. This may be recorded in the Hunt Library resources or using your own equipment. The grade for these presentations will be composed of a score from the instructor and your student peers. Detailed guidelines will be provided midsemester. Academic Integrity Plagiarism/cheating will not be tolerated. Teamwork on homework is encouraged (as an important part of being a successful engineer). Online quizzes must be completed by the student to whom they are attributed. You are expected to fully understand and take responsibility for any assignments you submit even though you may work on them with your classmates. Assistance or communication of any kind during exams is strictly forbidden. If an Academic Integrity violation is suspected, the instructor will follow the university discipline and reporting recommendations. If you encounter an ethical quandary with regards to your own work or the work of others, please consult the instructor. Instructional Objectives We aim to produce students with a foundation and working knowledge of basic electromagnetic phenomena. Chapter 1-8 of textbook “Fundamentals of Applied Electromagnetics” will be covered. Student learning objectives include: 1. Explain the following concepts: transmission line, phase velocity, phase constant beta, attenuation constant alpha, complex propagation constant gamma, characteristic impedance, wave (input) impedance, voltage reflection coefficient, traveling vs standing waves, and standing-wave-ratio. 2. Calculate the characteristic impedance, capacitance, inductance, resistance, and conductance of TLs. 3. Convert a wave solution equation from phasor-domain to time-domain notation. 4. Explain the concepts of permittivity, permeability, electric field (E-field), electric flux density field (Dfield), magnetic flux density field (B-field), magnetic field (H-field), divergence operator, and curl ECE 303 – Electromagnetic Fields Page 2 of 3 Dr. Qing Gu ECE-303 – Course Syllabus operator – with equations where appropriate. 5. Determine the electric field (Coulomb’s Law) and potential from discrete charges. 6. Apply Kirchhoff’s Voltage Law (integral form) relating voltage potential and electric field. 7. Explain and calculate capacitance, resistance, conductivity, and conduction current. 8. Explain and analyze Maxwell’s equations 9. Manipulate Maxwell’s equations to obtain boundary conditions, the conversation of charge, and electromagnetic wave equations. 10. Calculate the force and torque on charges and steady-state currents within magnetic fields, and the force between two current-carrying circuits. 11. Apply Biot-Savart Law to find the H-field from steady-state currents. 12. Explain the concepts of induced voltage (i.e., electro-motive-force), inductance, total magnetic flux, magnetic dipole, plane wave, spherical wave, intrinsic impedance, refraction, critical angle – with equations where appropriate. 13. Discuss Maxwell's equations and recognize the difference between electrostatics and electrodynamics. 14. Determine electromagnetic plane wave parameters, including propagation direction, wavenumber (i.e., propagation constant), absorption coefficient, frequency, wavelength, polarization state (i.e., linear, circular, elliptical) – from both phasor- and time-domain representations. 15. Apply Maxwell’s equations and wave equations in transmission/reflection problems. 16. Apply Snell’s Laws to find the refracted and reflected angles at a dielectric boundary, as well as when totalinternal reflection occurs. 17. Solve electromagnetic wave equations. 18. Understand wave propagation in guided geometries. 19. Explain, in the context of an oral presentation, how an electromagnetic device or system works, and evaluate peers doing the same.
