Study EM IF you
missed class. Please fill out homework return permission sheet. You can find
it on www.ece.utah.edu
(Undergrad-Forms). Turn it in to the ECE office. You need to do this again
EACH YEAR. If you are
a transfer student new-to-the-U, Welcome! Please make an appointment with Arlene to review your transfer
classes. |

(When you see this
little icon, it means I think there is something cool here that will make you
think!) How are E and H fields measured? OK, that part about
‘no magnetic charges’? Check this out… |
Portfolio 2: What are electric
and magnetic fields, and what causes them? (What are the sources?) What are
their units, and the units on all related constants? What do I turn in? Answer the portfolio question in words and equations (approx half to 1 page). This should be like a mini textbook section, written in your own words, that you can later use on the exam. Turn in the portfolio question, along with the Basic EM assignment shown above. When is this due? 9:30 am (start of class) on next lecture day. Where do I turn it
in?

NOTICE! |
As of today, I am changing the requirement to turn in homework daily. From today on, the homework for each week will be due on Mondays. Please turn it in in class, or in the homework locker before class. Please label each homework according to the number in the lecture website (the left-most number in the row for each day). Staple the portfolio to the homework problems for that day. This means that you will typically turn in three 'packets' each Monday. Portfolio/HW that was assigned Monday (the previous Monday) (staple), Portfolio/HW assigned Wed (staple), and Portfolio/HW assigned Fri (staple). If we do not have class on Monday (like this week), turn it on Wed instead. Thank you! |

Due before end of semester: PLAN YOUR FINAL
PROGRAM OF STUDY (now through graduation, indicate which technical
electives you will take. Be as specific as possible. This is important to be
sure you take the prereqs for the electives you want.). (YES, it is REQUIRED.
Any student who does not turn this in will be given an ‘incomplete’ grade in
this class until it is turned in. If
for some reason you think this should not apply to you (grad students, nonECE
majors, etc.), see me.) Spreadsheet
resources are available on the department advising website. It is STRONGLY recommended that you meet
with a faculty member (the website has a list of your pre-assigned faculty
advisor, or go to one in your technical
area of interest). |

from V and V from E? Homework #23: Textbook problems 4.33,34 REQUIRED

Shuttle Bus Ride (good for 1 days’ homework and portfolio)

If you would like to see how electromagnetic channel measurements
are made, come take a ride on the shuttle bus. One of my graduate students (Sai) will be collecting data for
his MIMO research for his PhD
dissertation-- measuring the channel in the bus as people get on/off, turn
their phones, etc. on/off, and otherwise change the channel environment. He is looking for a channel with Cauchy noise and is quantifying
the effect of the bus structure on the signal and noise. Come check it out, and bring your cell
phone. NOTICE! The Bus Ride Has Been Cancelled (we found the data we needed in a
paper). |
Turn in a
note with some interesting fact or observation from the experience. Get Sai
to sign it to say you were there. Turn it in to the homework locker. |

Bioelectronics
and the Bionic Age: How Technology
Touches Our Hearts and Minds |
Dr. Furse will be doing the
2009 University of Utah Reynolds Lecture.
Each
fall, Continuing Education at The University of Utah presents the annual
Frederick W. Reynolds lecture in order to answer hard questions, provide
insight into exciting aspects of the University and give the community a
glimpse into the future of higher education in Utah. For
decades the Reynolds Lecture has been an essential part of the U and
Continuing Education. Many distinguished university faculty members have
taken part in the annual lecture, always providing a stimulating (and
sometimes controversial) evening for audience members. By opening the
Reynolds Lectures to the general public, the series also serves as a way to
open the University and academia to the community, providing a forum for
citizens to learn more about what is happening at the U. Throughout the
years, the Reynolds Lecture has remained true to Continuing Education's
mission by fulfilling the charge to extend university and learning
opportunities into the community. |
Turn
in a note with some interesting fact or observation from the lecture. Get a
professor (any prof) to sign it to say you were there. Turn it in to the
