“Interactive lecture” supplemented by computer labo
ratory work and projects.
Daily D2L quizzes will begin on August 2

Course web page:

http://ecen3613.okstate.edu. Currently being updated. Projects and D2L will be
coordinated through this page.


Attendance policy:

You are responsible for all material

covered in the lectures. You will not receive
credit for computer laboratory classes that you miss.


Objective:

Understanding of the relevance of electromagnetic theory to all aspects of modern
electrical engineering. This includes application of vector c
alculus, energy storage
in static electric and magnetic fields, energy transfer in time
-
changing
electromagnetic fields (both in space and on transmission lines) and basic antenna
concepts.


Prerequisites:

Circuit analysis, vector calculus, differential eq
uations

Grading:

F

hour exams, a comprehensive final exam,
projects, and D2L quizzes.

The final grading scale wi
ll be determined at end of the semester. An approximate
scale will be given after every exam based on only that exam's scores.


The instructor reserves the right to replace the D2L quizzes with traditional
homework problems at any time during the semester.

Otherwise, homework will
not be collected. Suggested homework problems will be given each week, and the
answers (not solutions!) will be distributed. Time will be taken each week to
discuss the homework problems.





ACADEMIC INTEGRITY POLICY


You must ob
serve all aspects of professional conduct that is expected of a successful practicing
engineering in this course. In particular, any individual assignment that you submit must be entirely your
own work, and any group assignment must be the result of the co
llective efforts of only that project
group. Accordingly, any violation of the OSU Academic Integrity Policy will result in failure of the
course. This in
cludes, but is not limited to,
copying from another student, copying materials posted on the
web, or c
opying materials submit
ted by students in previous sem
esters. The complete OSU Academic
Integrity Policy is available at http://academicintegrity.okstate.edu. Note that aiding another in violating
the policy is an equivalent violation itself.
