            Hwk 6 will be posted tomorrow (Wed) and is due on Friday Dec. 2nd in recitation session
11-20:  We do not have lab in this week.
11-19:  For those of you that see ee166f under your ACMS account, you must type 'ee166f' into terminal to have access to ADS. If you have an ee166fXX account ignore this post
11-17:  Office Hours are cancelled today (Prof. Rebeiz is on travel, and lecture will be given by another professor)
11-13:  The bottom of this webpage holds a large list of helpful ADS links
            Note on Hwk 6, Problem 3: "The mention of Problem 2a refers to the matching problem in Hwk3"

11-04:  Review Session is Saturday at 5-630pm in Room 4309/Jacobs Hall. The code for the door is: 109626
10-29:  Midterm exam is coming on Tuesday Nov. 8. Please start preparing for it this week, by the old exams and old homework problems, and asking me                     and the TAs questions when you hit a snag. We are here to help and this is the week to do it. Nothing is better for mastering the Smith Chart,                         impedance matching and S-parameters than just doing a lot of problems. Learning hard material is just like driving: The best drivers are the ones                     who practice a lot (and make their share of mistakes) on protected roads. Or like Tennis or Soccer or Baseball or etc: you have to practice a lot.                         Nothing is better than practice – there is no magic formula to replace it (we have not found it yet, not in education, not in sports, not in learning                     anything new). Practice and ask questions – we are here to help!!
             There is a lab in the week of October 31 also. 
10-25:  HW3 can be submitted either 10/27 (in class) or 10/28 in discussion. 
10-21:  Discussion will be held today still. Bring a smith chart or two to follow along.
10-19:  Homework 3 will be posted on Thursday October 20

            There is no lecture on Thursday October 20. Prof. Rebeiz is on travel and he will do a make-up lecture later.

            There is Lab 2 in the week of October 24.

10-16:  Write your name clearly on the homework or we cannot give you a grade.
            Box your solutions (when appropriate) so that we know where to find it.
            Homeworks must be written only in black or blue Ink. Color and Pencil are only acceptable on the Smith Chart.
            Graded homeworks to be picked up in the lab once you have a lab session.
10-14:  We are not going to have lab next week.  The next lab will be in the week of Oct. 24.
10-11:  Prof. Rebeiz is finding a lot of your emails in the SPAM folder. Please start the subject line with “ECE166: ..... ” in every email sent to Prof. Rebeiz or                       the TAs
10-08:  Send all lab conflicts directly to Nikhil to resolve.
            Lab 1 is Monday-Thursday October 10-13. Please come to your lab session. Attendance is mandatory.

10-01:  Please follow this link and download Matlab for your UCSD work.
09-30:  Send Prof. Rebeiz an email if you want to change labs (last chance)
            As discussed, no pencils allowed. Homeworks written in pencil will be returned ungraded.
            Matlab is recommended for the homework assignments, and you can get a student version from the bookstore, or download a student version from the web (for a small fee). I am also working with JSOE to give you access to Matlab, but this may be on JSOE computers only. Will announce in class. (you can use other software if you wish, but Matlab is recommended).   
09-29: Hwk 1 is now posted
           There is a recitation lecture on Friday Sept. 30. Please attend

           There is no lab in the week of October 3-7

Thoughts for the homework:

The homework will be graded very generally.  That is, we will assign 10, 8, 6, 4, 2, and 0 as grades with the following guidelines: 10 (Well done to mostly done), 8 (few things are lacking), 6 (about half of it is done), 4 (about half is done), 2 (most things are not done) and 0 (lacking or homework is not given).  Late homework are not allowed unless by permission from instructor by email.

Academic dishonesty


Cheating, plagiarism and any other form of academic dishonesty will not be tolerated. This includes cheating on exams, using resources that are not allowed, copying lab reports or results, copying all or part of another group’s simulations or bread boards, lying to tutors/TAs or instructor, aiding in plagiarism or cheating, or any form of dishonesty. You may help each other with the homework (it does not need to be handed in). On the labs, you may consult each other. For example, you can ask how someone else went about solving the problem. You should not copy their solution or allow your solution to be copied. Once you have solved a problem yourself, you may compare and discuss. In short, you should do the work yourself and you can ask assistance from others. The TAs and tutors give you the same level of support (and this is a good yard stick for you to know what is allowed in terms of helping and what is not). Never claim work/ideas to be yours if they are not, and never assist others in cheating (e.g. by offering them your solutions). If you are not sure of what is allowed, ask the instructor. Wrong assumptions are never an excuse. There is a zero tolerance policy. Cheating on labs results on a zero credit on all labs; cheating on quizzes, the final exam or multiple labs will result in a possible F in the class. All cases of cheating will be reported to the department and your college. You risk possible suspension from UCSD.
