Course Information: Number: EET 492 Title: Electromagnetic Fields and Waves Credit: 3 credit hours Time: 3:00-5:30 F Prerequisites: by permission from instructor Text book: Field and Wave Electromagnetics, 2 nd Ed. by D. K. Cheng, 1989 ISBN: Ref: Lecture notes: the most important reading materials Course Description: This junior course is an introductory course to electromagnetic fields and waves. Classical topics that will be covered in the course include essential mathematics; electrostatics; magnetostatics, time-varying fields; Maxwell s equations; transmission lines; waveguides and resonators; antennas and radiation. Course Overview: Electromagnetics is a prerequisite for many applications in electrical engineering. With exploitations of high frequency, broadband spectrum and high data rates, it is hard to find a device that works entirely without electromagnetism. A good understanding of electromagnetic fields and waves will absolutely benefit students of science and engineering in their future development both in academic fields and in industry: biomedical engineering and biotech; physics based signal processing and imaging; computer chip design and circuits; electronic systems; photonics and laser engineering; wireless communications and propagation; MEMS and microwave engineering; Radar engineering, RCS 1

Homework: There are biweekly homework assignments with questions related to the topics covered in the class. There are about 8 assignments. Solutions will be provided later. No homework submissions will be accepted once the solutions have been posted. Examinations: There will be two take-home exams in the course: a midterm exam and a final. The final exam will be cumulative. Grading: The breakdown of the final grade is as follows: Attendance 20% Homework 40% Midterm exam 20% Final exam 20% 3

4 Class participation and discussions and random quizzes may contribute to up to five bonus points. Final grades are based on A B C D 0-59 F Students should keep track of their scores and discuss with the instructor if they have any concerns. Collaborations: Students are encouraged to discuss any related topics in and after classes, with classmates and/or with the instructor. Active discussions may give students bonus points that may contribute to the final scores. Students may not copy solutions from anyone or anywhere. Any materials that are submitted must be the students own work. Absences: Students are required to attend every class. Random quizzes may carry bonus scores that may contribute to the final scores. Incompletes, Withdrawals, and Drops: Incompletes are given out only under extreme circumstances. If a student is running into problems with the course, please contact the instructor as early as possible so he/she will not fall behind. This course falls under all University policies for last day to drop courses, etc. Please see the Course Catalog for information on University services and policies. Please see the academic calendar for course dates, the last day to drop courses without penalty, and for financial disenrollment dates. Academic Honesty: Each student is expected to maintain the highest standards of honesty and integrity in academic and professional manners. No cheating or plagiarism. From USM Bulletin: When cheating is discovered, the faculty member may give the student an F on the work involved or in the course. If further disciplinary is deemed appropriate, the student should be reported to the Dean of Students. In addition to being a violation of academic honesty, cheating violates the Code of Student Conduct and may be grounds for probation, suspension, and/or expulsion. Students on disciplinary suspension may not enroll in any courses offered by The University of Southern Mississippi. Professionalism: Students are required to maintain a professional attitude in the class. Any disrespect of professor and/or of students is not tolerated. ADA Statement: If a student has a disability that qualifies under the American with Disabilities Act (ADA) and requires accommodations, he/she should contact the Office for Disability Accommodations (ODA) for information on appropriate policies and procedures. Disabilities covered by ADA may include learning, psychiatric, physical disabilities, or chronic health disorders. Students can contact ODA if they are not certain whether a 4
