Introduction In this course you will learn about the propagation of electromagnetic (EM) waves in unbounded media as well as in waveguides and transmission lines. The foundation is the set of Maxwell’s equations together with EM field behavior in physical media. A basic understanding of Maxwell’s equations and vector fields as taught in ELEC3105 (prerequisite) and differential and integral calculus as taught in MATH 2004 is assumed. The lecture material will be reinforced in weekly PA sessions. Textbook There is no compulsory textbook – course notes are available on the course website. There are many excellent reference books for the course. Some recommended ones are: U.S. Inan and A.S. Inan, Electromagnetic Waves, Prentice Hall 1999 U.S. Inan and A.S.

PA Session (3 hours per week, Thursday 2:00-5:00 pm ME3174) Problem sets will be assigned every week. Be prepared for the PA by attempting the problems before the PA session. The first 2 hours of each PA will be used to answer your questions and do sample problems. In the last hour of the PA there will be a quiz based on the current problem set. PAs start May 12. All students must write at least 4 of the 5 quizzes and get at least 50% on the final exam to pass the course. Course Grade The final grade will be determined using the following weighting. Best of:
Final exam 60% Quizzes 40% (best 4 out of 5)
or
Final exam 100%
The final examination is for evaluation purposes only and will NOT be returned to the student. Plagiarism Plagiarism is a serious instructional offense that will not be tolerated. It involves passing off someone else’s original work as your own. Most cases of plagiarism can be avoided by carefully citing sources for any ideas, statements, results etc. that are not your own. Please refer to the section on instructional offenses in the Undergraduate Calendar for additional information. Academic Accommodation You may need special arrangements to meet your academic obligations during the term. For an accommodation request the processes are as follows: Pregnancy obligation: write to me with any requests for academic accommodation during the first two weeks of class, or as soon as possible after the need for accommodation is known to exist. For more details visit the Equity Services website: http://carleton.ca/equity/accommodation/student_guide.htm Religious obligation: write to me with any requests for academic accommodation during the first two weeks of class, or as soon as possible after the need for accommodation is known to exist. For more details visit the Equity Services website: http://carleton.ca/equity/accommodation/student_guide.htm Students with disabilities requiring academic accommodations: in this course must register with the Paul Menton Centre for Students with Disabilities (PMC) for a formal evaluation of disability-related needs. Documented disabilities could include but are not limited to mobility/physical impairments, specific Learning Disabilities (LD), psychiatric/psychological disabilities, sensory disabilities, Attention Deficit Hyperactivity Disorder (ADHD), and chronic medical conditions. Registered PMC students are required to contact the PMC, 613-520-6608, every term to ensure that I receive your Letter of Accommodation, no later than two weeks before the first assignment is due or the first in-class test/midterm requiring accommodations. If you only require accommodations for your formally scheduled exam(s) in this course, please submit your request for accommodations to PMC by the last official day to withdraw from classes in each term.
