ECEN 3400, ELECTROMAGNETICS, Spring 2014

Prof. Milos Popovic, EE 1B48, 2-5304

 

Welcome to electromagnetics!

I hope you will learn how to like this topic as much as I do.

 

Weekly updates, Monday, Apr 7:

·         Project #1 posted Apr 8, due Apr 28.  This will be the only project assigned; see updated grading scheme below.

·         HW5 due this Friday, Apr 11.

·         Lecture slides up through today.

·         MIDTERM 2 review session during office hours this week and 1h after that:  Friday, Apr 11, 3-5pm.  Location TBA (will be posted on my office door and emailed to class).

·         This section will contain various updates each week releavant to the class as the semester progresses.

·         Thinking ahead a bit:  Here is a formula sheet. You are expected to understand and know these formulas by the final exam (closed everything, no calculators): EM-Formulas.pdf

If you do not like the textbook, there are many other books you can look at - these are available at the library or online. These are good, but are different in style from the one we will use are:

-          B. Notaros, Electromagnetics, Pearson, 2011.

-          D. Cheng, Fundamentals of Engineering Electromagnetics, Addison Wesley.

-          W. Hayt and J. Buck, Engineering Electromagnetics, Prentice Hall (8th ed.)

-          S. Marhsall, R. DuBroff, G. Skitek, Electromagnetic Concepts and Applications, Prentice Hall. (physics textbook)

-          Ramo, Whinnery and Van Duzer, Fields and Waves in Communication Electronics, Wiley.  (higher level)

They all contain the same material, but the notation might be slightly different.

Homework Assignments

Homework will be due every other Friday in class. I advise that you start working on it as soon as it is assigned, since it covers two weeks worth of material.

Midterm and final exam problems:

·         At the end of the syllabus is a list of problems from the Workbook that will be either given for homework; worked out in recitations; or left as exercise. ONLY these problems will be on the midterm and final exam.

·         The list will be probably modified slightly as we go through the semester. Please pay attention; I will note any modifications in the weekly news. At times, I will assign a problem that is not in the workbook and this problem is also eligible for the exams.

 

Copying other students’ work, or letting other students copy your work is considered dishonest and if proven will result in and F in the course. I am sure you have already been told that this is for your own good.

Schedule

-          Below is the approximate class schedule and exact homework schedule for the semester. It will be updated as needed, so please check periodically.

Policies and Regulations:  The following policies and regulations apply for this course.

 

Honor Code. All students of the University of Colorado at Boulder are responsible for knowing and adhering to the academic integrity policy of the institution. Violations of this policy may include: cheating, plagiarism, aid of academic dishonesty, fabrication, lying, bribery, and threatening behavior. All incidents of academic misconduct shall be reported to the CU Honor Code Council (honor@colorado.edu, 303-725-2273). Students who are found to be in violation of the academic integrity policy will be subject to both academic sanctions from the faculty member and non-academic sanctions (including but not limited to university probation, suspension, or expulsion). Other information on the Honor Code can be found at
 
http://www.colorado.edu/policies/honor.html  
http://www.colorado.edu/academics/honorcode/

 

The instructor reserves the right to use anti-plagiarism software to help determine the originality of term papers.

 

Cell phones and PDAs. Out of respect for the students and instructors as well as to minimize interference to laboratory measurement it is mandatory that cell phones or other devices with annunciators or other disturbing audio capabilities be turned off before entering the classroom or laboratory. Calculators may be used during exams, but personal digital assistants or other devices with communications capabilities are not permitted.

 

Disability. Students who qualify for accommodations because of a disability should submit to the instructors a letter from CU Disability Services in a timely manner so that needs can be addressed.  Disability Services determines accommodations based on documented disabilities.  Contact: 303-492-8671, Willard 322, or http://www.colorado.edu/disabilityservices .
 
Religious Observances. Campus policy regarding religious observances requires that faculty make every effort to reasonably and fairly accommodate all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance. Conflicts between scheduled course activities and religious observances should be made known in writing to the instructors at least two weeks in advance of the activity so that alternate arrangements can be made. See full details at http://www.colorado.edu/policies/fac_relig.html .
 
Discrimination and Harassment. The University of Colorado at Boulder policy on Discrimination and Harassment (http://www.colorado.edu/policies/discrimination.html), the University of Colorado policy on Sexual Harassment, and the University of Colorado policy on Amorous Relationships applies to all students, staff and faculty.  Any student, staff or faculty member who believes s/he has been the subject of discrimination or harassment based upon race, color, national origin, sex, age, disability, religion, sexual orientation, or veteran status should contact the Office of Discrimination and Harassment (ODH) at 303-492-2127 or the Office of Judicial Affairs at 303-492-5550.  Information about the ODH and the campus resources available to assist individuals regarding discrimination or harassment can be obtained at http://www.colorado.edu/odh .
