Problem 2: The integral to determine the force is best done numerically. You are trying to figure the sign of the force, so you may set I0=1, c=1, radius a=1, n=1.5 and alpha=0.1. I would suggest making a plot of the integrand from -a to a to help you see the contribution of the different ray heights. This way you can see how it all cancels when the intensity profile is uniform.

Problem 4 (HM6.3): the condition for zero reflection should relate the vacuum wavelength of the incoming light to the index and thickness of the thin layer.

14 Sept 2007

HW 4 is posted below.

13 Sept 2007 Notes for all lectures to date are scanned in. The treatment of polarization I did in class is slightly different from the notes.

HW3: I made a figure for problem 2 that may help you visualize the coordinates. Reading my lecture notes will probably help you with some of the terminology.

31 Aug 2007

HW 2 is posted below. Hopefully you will find this more straightforward.

> Notes for the early lectures are posted below. Remember that there are often more complete derivations in there, so you might consider them as an additional reading. resource.

>HW1 HM problem 4.12 In this problem, solve for Q(t) first. The Maxwell equations you are using are given in equations 4.21-4.24. The second set on that page are for microscopic EM, where there are no bound charges or dielectric media. So in our context, there is no free current, only the displacement current.

> I've posted a couple of links below to give some more documentation on vector ID's. If any of you find anything useful, please post it. Many pages I found were more specific to the use of the notation in relativity, which is more involved than what we are interested in at this time.

> I will be at the SPIE conference in San Diego to give a talk. I'll be leaving after class on Monday, returning Tuesday night. No change in class schedule, but I'll move tuesday's office hour. Next week: office hours W1-3, Th1-4

> During the week of 3-7 Sept, I'm in Santa Fe to give a talk and poster. Dr Kowalski will be teaching in my place.

> I've posted HW1 below. Also look at the pdf from an intro plasma physics book by Chen. Later, I'll post copies like that in the forum section. --Ayuffa 06:21, 24 September 2007 (MDT)--Ayuffa 06:21, 24 September 2007 (MDT)
