will contain PDF copies of the lectures by Prof.
as they are delivered during the spring of 2015. The content of the files “Lecture #”
is what was written on the screen of room 306. Also here you can find the
scanned lectures of the professor based on his notes, with far more detail.
Also additional material, such as some scientific papers discussed in class,
are included in this web page.
Week 1 (Thursday Jan. 8) Lecture 1
Week 2 (Tuesday Jan.13) Lecture 2
(Thursday Jan.15) Lecture 3 Professor’s notes on Green functions are
in the scanned notes for Chapter 1 above.
Week 3 (Tuesday Jan. 20) Lecture 4
(Thursday Jan. 22) Lecture 5
Week 4 (Tuesday Jan. 27) Lecture 6
(Tuesday Jan. 29) Lecture 7
Week 5 (Tuesday Feb. 3) Lecture 8
(Thursday Feb. 5) Lecture 9
Week 6 (Tuesday Feb. 10) Lecture 10
(Thursday Feb. 12) Professor lectured on the early sections of Chapter
5 but smart board was not working, thus the whiteboard was used. We made it
to the example in Section 5.5, formula 5.36.
Week 7 (Tuesday Feb. 17) Students working on first midterm exam.
(Thursday Feb. 19) Lecture 11
Week 8 Both lectures cancelled because of weather L
Week 9 (Tuesday March 3) Lecture 12
(Thursday March 5) Lecture 13
Week 10 (Tuesday March 10) Lecture 14
Note: Fixing a gauge is more subtle than usually believed. A discussion can be
found in this Wikipedia link “Gauge Fixing” . In non-abelian theories, gauge
fixing may lead to the Gribov ambiguity where an apparently good gauge may
not intersect a gauge orbit or may do it more than once. See Gribov ambiguity
(Thursday March 12) Lecture 15
Week of March 16-20 SPRING BREAK!!
Week 11 (Tuesday March 24) Lecture 16
(Thursday March 26) Lecture 17
Week 12 (Tuesday March 31) No lecture because of second mid term exam.
(Thursday April 2) Lecture 18
Week 13 (Tuesday April 7) Lecture 19
(Tuesday April 9) Lecture 20
Week 14 (Tuesday April 14) Due to the projector system malfunctioning
I had to give this lecture on the whiteboard. Fortunately, the analogous lecture
delivered last year is very close to the present one. So here is the 2014 lecture Lecture 21
In class we discussed briefly the possibility of having antennas made out of several dipoles pointing along the z axis,
that could be all located in the xy plane at some distance from each other related with the wavelength, or they could be phase shifted, leading to a variety of patterns, including a cardioid and also a “beam” i.e. unidirectional radiation.
You can find my notes on this subject in the following file
These notes were based on many sources including
In class we followed
the correction factor 1/(1-v/c). We also used the limit from a “cloud” charge distribution rho to a point charge q.
HOWEVER, this is not needed. There is a rigorous mathematical derivation that starts with a “delta” function
for the charge and arrives perfectly to the correction factor. The information is in the following link:
(Tuesday April 16) The projector equipment still not working, thus I cannot
display here the lecture, but the one of last year is close: Lecture 22
Week 15 (Tuesday April 21) Projector finally working well. Here is the lecture: Lecture 23
(Thursday April 23) ) Lecture 24 This was the last lecture of the semester!!
