Prof. Zoya Popovic, OT 252, 2-0374

 

Welcome to electromagnetics!

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

Weekly updates, Monday, November 13th, 2017:

·         Midterm 2 is scheduled for November 15th (Wednesday) before Fall Break.

o   Timing: 6-8pm, 1B-32 [or 3-4pm 1B-32 and 4-5pm in my office]

o   Please check the list of questions and problems – they have been updated for Chapters 12 – 17.

o   The midterm is cumulative, so expect a small part of it to be from Chapters 3-11, but most from Chapters 12 – 17.

o   Same format as Midterm 1, more time.

o   You are expected to know all the formulas we covered so far from the formula sheet: EM-Formulas.pdf

·         No class on Friday, November 17tt.  Happy Thanksgiving!

·         HW6, due Monday, December 4th, in class (covers only Chapter 18):  HW6-ECEN3400-F2017.pdf

·         HW7 (last one, Chapters 19 to end), due December 13th, in class:HW7-ECEN3400-F2017.pdf

·         Project 3 due December 13th, in class (last class):  Proj3-ECEN3400-F2017.pdf

·         Review sessions:

o   Monday, November 13th (4-5/5-6pm), for Midterm 2

o   Monday, December 11th (4-5/5-6pm)

o   Wednesday, December 13th, in class

·         Extra office hours:

o   Friday, December 15th, 3-5pm

Textbook

You will have a free textbook this semester.

[The authors are Popovic2 , publisher Prentice Hall, 2000. So, you can blame me directly if you do not like it. At least it is free. You can also borrow a version in Korean from me! (Though I cannot guarantee the content.) ]

If you do not like the textbook, there are many other books you can look at in my office at your convenience, and if you like one, you can check it out of the library or buy it. Some books that I like, but are different in style from the one we will use are:

-          B. Notaros, Electromagnetics, Pearson, 2011.This book is used for ECEN 3410.  

-          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.

Midterm and final exam problems:

·         At the end of the syllabus is a list of problems from the book that will be either given for homework; worked out in recitations; or left as exercise. These problems will constitute >90% of each exam, so if you know how to do all of them, you are guaranteed an A. Start working on them right away!

·         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.

-          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 .
