Class organization and rules: 

-        There will be 10 experiments this semester. You must complete all of these to pass the course. There will be a single make-up lab session near the end of the semester only for students that miss a lab for a good reason and who inform me ahead of time.

-        If you arrive more than 10 minutes late for your lab section, you will not be allowed to do the lab, and will have to make it up during the make-up week.

-        A prelab homework is due at the beginning of your lab section each week. Be sure to do the homework appropriate to the lab that your group will be doing each week.

-        You will not be allowed to do the lab work (and hence will not get credit for that week's experiment) unless the pre-lab has been handed in at the beginning of the lab. The pre-labs are designed to help you finish the labs.

-        Lab reports are due in your next lab session (one week after you do the lab).

-        Although you carry out the lab experiments in groups, everyone must turn in their own individual lab report that shows your own understanding of the material. Only the data you took should be the same among reports from the same lab group.

-        Grading of pre-labs and lab reports is as follows: 10 – complete and all correct; 8-9 – complete and mostly correct; 5-7 – complete but some errors; 3-4 – complete but mostly wrong; and 0-2 – incomplete or wrong.

-        There will be a 1-hour written and a 20-minute lab oral final exam. The lab oral exams will be during the last week of the semester.


Recommended textbook: Pozar.

Additional material will be provided when needed.

Background text (free): Introductory Electromagnetics, Popovic and Popovic, on ECEN3400 web page, and Electromagnetics by B. Notaros.


Software:  In this class we will use an industry-standard   circuit simulator tool from National Instruments Applied Wave Research (AWR): Microwave Office. NI/AWR has generously allowed our class to obtain free licenses. Please follow the instructions below to obtain a license for your computer:

  1. Go to
  2. If for some reason you have previously already registered on the AWR website, you will use the same account to get the software.
  3. If you have not previously registered, the license generation will send you an email with the account login information.
  4. You will then obtain a license file with a link to the software download area.

If you are asked for a faculty contact name, use "Prof. Taylor Barton". It is best if you download from an on-campus location, or use a VPN. The domain "" is added to the system so you should not have any problems, but please let me know as soon as possible if you have trouble downloading the software. The AWR software runs on Windows only. If you run another OS, you will have to run it in a virtual machine.


Grading (preliminary)

Homework and Prelabs



Lab Write-ups



Midterm Exam (written)

Final Exam (written portion: covers the entire course)



*Note that the total is 110%, and the grade is based on 100% (built-in curve)


Copying other students’ work, or letting other students copy your work is considered dishonest and if proven will result in an F in the course.  


Below is the class and homework schedule for the semester. It will be updated as needed, so please check periodically.

Policies and Regulations: 


This course strives to provide the student with a variety of specific learning outcomes. These include the student outcomes identified by ABET, and adhered to by the ECEE department, related to the skills, knowledge, and behaviors that students acquire as they progress through the program.  The specific Student


Cell phones and PDAs. Out of respect for the students and instructors as well as to minimize interference to laboratory measurement it is mandatory that cell phones or other devices with annunciators or other disturbing audio capabilities be turned off before entering the classroom or laboratory. Calculators may be used during exams when explicitly allowed, but personal digital assistants or other devices with communications capabilities are not permitted.


Electronic Communication. Questions on the course material, schedule, or policies may be e-mailed to the instructor at the above-listed address. E-mailed questions will be addressed as soon as possible, although given the volume of e-mail received by the instructors a delay of up to several days may occur. All course-related e-mails should include the course number in the subject line. Other forms of communication (voice mail, electronic communications other than email or from non-CU email addresses, etc.) are not guaranteed a response.





If you qualify for accommodations because of a disability, please submit your accommodation letter from Disability Services to your faculty member in a timely manner so that your needs can be addressed.  Disability Services determines accommodations based on documented disabilities in the academic environment.  Information on requesting accommodations is located on the Disability Services website. Contact Disability Services at 303-492-8671 or for further assistance.  If you have a temporary medical condition or injury, see Temporary Medical Conditions under the Students tab on the Disability Services website.



Students and faculty each have responsibility for maintaining an appropriate learning environment. Those who fail to adhere to such behavioral standards may be subject to discipline. Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with race, color, national origin, sex, pregnancy, age, disability, creed, religion, sexual orientation, gender identity, gender expression, veteran status, political affiliation or political philosophy.  Class rosters are provided to the instructor with the student's legal name. I will gladly honor your request to address you by an alternate name or gender pronoun. Please advise me of this preference early in the semester so that I may make appropriate changes to my records.  For more information, see the policies on classroom behavior and the Student Code of Conduct.



All students enrolled in a University of Colorado Boulder course are responsible for knowing and adhering to the Honor Code. Violations of the policy may include: plagiarism, cheating, fabrication, lying, bribery, threat, unauthorized access to academic materials, clicker fraud, submitting the same or similar work in more than one course without permission from all course instructors involved, and aiding academic dishonesty. All incidents of academic misconduct will be reported to the Honor Code (; 303-492-5550). Students who are found responsible for violating the academic integrity policy will be subject to nonacademic sanctions from the Honor Code as well as academic sanctions from the faculty member. Additional information regarding the Honor Code academic integrity policy can be found at the Honor Code Office website.



The University of Colorado Boulder (CU Boulder) is committed to fostering a positive and welcoming learning, working, and living environment. CU Boulder will not tolerate acts of sexual misconduct (including sexual assault, exploitation, harassment, dating or domestic violence, and stalking), discrimination, and harassment by members of our community. Individuals who believe they have been subject to misconduct or retaliatory actions for reporting a concern should contact the Office of Institutional Equity and Compliance (OIEC) at 303-492-2127 or Information about the OIEC, university policies, anonymous reporting, and the campus resources can be found on the OIEC website.

Please know that faculty and instructors have a responsibility to inform OIEC when made aware of incidents of sexual misconduct, discrimination, harassment and/or related retaliation, to ensure that individuals impacted receive information about options for reporting and support resources.



Campus policy regarding religious observances requires that faculty make every effort to deal reasonably and fairly with all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance.  In this class, the instructor must be informed at least two weeks in advance of a conflict with an exam or laboratory session, so that accommodations can be made. For missed laboratory sessions due to religious holidays, the student will be allowed to work with another lab group on a date that does not conflict.


See the campus policy regarding religious observances for full details.
