of the Casio FX 991 calculator”.
(ii)
A sample final exam
is posted under the section ‘Final Exam’.
(iii)
Please do the
course evaluation before Dec. 7. Your feedback is important to me as it would
help improve the course.
(iv)
Next week there
will be review lectures on Dec. 4 and Dec. 6. Final exam question formats will
be discussed.
(v)
Since many of
you had trouble with assignment 4, the deadline for the submission of
assignment 4 is extended to Nov. 29.
Today, in the class, I will give some tips.
(vi)
There is a
makeup lab (for lab3 and lab4) in this week. Please contact the TA Neil Acton
to schedule the makeup lab.

more information on Lab 4.
(xi)
Lab3 issue: You
are required to study the materials needed to do lab3 by reading the manual on
transmission line (unit 1) before going to the lab. Some of you are
spending hours studying the material there and then do the lab. Obviously, you
cannot finish it in 3 hours. You should start doing the lab work immediately at
2:30. The TA will not stay beyond 5:20 pm.
(xii)
If you miss the
lab for a valid reason (with an MSAF), please contact the assigned TA (actonn@mcmaster.ca). He will try to find an alternate time.
(xiii)
Quiz 2 will be
on Nov. 3. It will be done during the tutorial. The duration of quiz is about
30 minutes. The TA will write the question (and the required formulas)
on the board. Please bring paper
and pen. If you write
in pencil, no re-marking.

(xvii)
If you cannot
write the midterm test, the weight of the midterm is added to final provided
that you have a valid reason. The other option is that there will be an oral
midterm test in my office after Oct. 24. The exact date will be announced
later. The difficulty level of the oral midterm is the same as that of the
(written) midterm test. The duration is about 20 minutes and questions could be
of the type, ‘explain’, ‘prove’ or doing an example calculation. I have a white
board in my office which you will use for the oral midterm. Please prepare for
the oral midterm just like you would do for the written midterm.
(xviii)
Please send me
an email if you are planning to appear for the oral midterm.
(xix)
The Matlab assignment #2 is due on Monday, Oct. 16. Please see
the section Assignments for more details.
(xx)
To study for
quiz, please look at the problems solved during the tutorials and lectures. The
worked examples posted at this website (see section Worked

Please read the section Labs
for more information on
Lab 2. There is no lab for L01,
L03, L05 in the week of
Oct. 16. Lab 3 will start only
after we cover
transmission lines.
(xxii)
Quiz 1 will be
on Sept. 29. It will be done during the tutorial. The duration of quiz is about
30 minutes. The TA will write the question (and the required formulas)
on the board. Please bring paper
and pen. If you write
in pencil, no re-marking.
Topic: Faraday’s Law and Displacement
current
Format: Similar to the problems
covered during the
tutorials.
(xxiii)
The deadline
for the assignment #1 submission is postponed to Sept. 25 due to unavailability
of the custom courseware at the bookstore. The assignment drop box is located
at ITB-A110.
(xxiv)

Final
Exam
There will be 7
questions:
2 or 3
questions – Explain or Discuss …. – Physics type – Math Optional
Please make sure
that you draw figures (if necessary) to explain the concepts. A picture is worth a thousand words.
2 or 3
questions – Show that or Derive …. – Math type
2 or 3
questions – Engineering examples – similar to the problems covered in tutorials
– you could use formula sheet.
Please see the
formula sheet below:
Midterm:
Midterm 2015:
Formula
sheet will be provided at the end of the exam paper.
Topics:
Everything
covered until Oct. 19.
Faraday’s Law
Displacement Current
Maxwell’s equations
Plane waves
Transmission Lines
Format:
There
will be three questions.
(i)
Explain … or Discuss …
- to test your conceptual knowledge. You need to describe in words. I
encourage you to draw figures, if applicable. Math is optional.
(ii)
Prove that … or Show that … - to test you math skills. You
need to derive from first principles.
(iii)
Engineering examples – similar to the problems discussed in
tutorial.
All these
questions would have roughly the same weights.
If you cannot
write the midterm for a valid reason, your midterm weight will be added to
final.
Matlab assignments:
In
total, there are four assignments. Three best assignments will be chosen. You
need to submit a hardcopy. Electronic copies are not acceptable. The purpose of
choosing three best assignments is to accommodate for illness, travel etc. So,
if you miss an assignment, you don’t need to fill up an MSAF. However, if you
are missing two or more assignments for a valid reason (supported by MSAF), the
weight of the missed assignment will be added to the other assignments.
The assignment
drop box is located at ITB-A110.

Quizzes
In total, there will be three quizzes and two best quizzes will be
used for evaluation. The purpose of choosing two best quizzes is to accommodate
for illness, travel etc. So, if you miss a quiz, you don’t need to fill up an
