Course Description:

The purpose of this course is to provide students with the background necessary to understand the interplay between electricity and magnetism, the electromagnetic wave properties and its propagation in different media through various junctions. Its applications on electromotor, transformer, signal transport in transmission line, impedance matching, cavity resonator, plasma oscillation, and antenna principles will be addressed.

Textbook:

Fundamentals of Engineering Electromagnetics, David K. Cheng (Addison Wesley Longman) or Electromagnetics for Engineers, Fawwaz T. Ulaby (Prentice Hall)

Prerequisite:

Familiar with Electromagnetic Fields and Waves from undergraduate physics and engineering courses. Be able to apply calculus and differential equations to solve problems. Some review will be provided.

Tentative topics:

Tentative topics is listed in my web site under Engr 297C. The list is intended to help students to prepare and review lectures, and not to encourage students to miss classes. Students are responsible for any material presented in lectures even though it might not be on the list.

Student Learning Objectives:

By the end of the course, each student should demonstrate the ability to:

1. predict the induced current due to a time-varying magnetic flux in a structure,
2. write down the electric field intensity in a medium if the magnetic field is known, or vice versa,
3. predict the behavior of the electromagnetic wave going through a junction of 2 media,
4. calculate simple problems associate with electromotor, power generator and transformer,
5. use transmission lines as circuit elements in high-frequency designs
6. design matching circuits using various techniques
7. calculate electromagnetic modes in resonators such as cavity, parallel plates and helix
8. predict simple plasma motions and electronic screening in free electron gas model
9. design simple antenna for RF signal transmission

Grading:

Distribution of points (homework 10%, In-class group exercise 10%, 2 mid-term each 20%, final 40%)

Final Letter grades will be assigned roughly according to the following percentage of maximum points earned as long as you pass the Laboratory section as well.

• A 85% or above
• B 70 - 85%
• C 55 - 70%
• D 40 - 55%
• F below 40%

Calendar:

Lectures: Oct 7, 21 & 28, Nov 4, 10, 17 & 18, Dec 1, 2, 9 & 16
no classes on: 10/14, 11/11 & 11/25
lmid-terms 11/4, 12/1 (tentatively)
lfinal exam 12/16

Missed Lecture:

If you should miss a lecture, please read up on the lecture slides posted on my website and study the relevant topics. In addition, please contact a classmate for any last minute announcement. You are responsible for any materials covered in class.

Late Homework or Exercise:

Since homework is due every week, if you miss a class, you’ll likely to miss the homework and in-class exercise. If you can turn them in BEFORE the solution is posted online, you’ll get full credit. Otherwise, your work will receive no more than half credit.

Missed Exam:

If you have to miss an exam, please make arrangement with me prior to the exam week. Otherwise, no make-up examination will be given unless proven critical medical emergency.

Academic Integrity Statement:

From the Office of Student Conduct and Ethical Development: "Your own commitment to learning, as evidenced by your enrollment at San Jose State University, and the University's Academic Integrity Policy, require you to be honest in all your academic course work. Faculty members are required to report all infractions to the Office of Student Conduct and Ethical Development." The policy on academic integrity.

Disabilities:

If you need course adaptations or accommodations because of a disability, or if you need special arrangements in case the building must be evacuated, please make an appointment with me as soon as possible, or see me during office hours. Presidential Directive 97-03 requires that students with disabilities register with the Disabilities Resource Center (DRC) to establish a record of their disability.
