Description          This is a graduate level electromagnetic course with exclusive focus on antenna theory and practice. The class covers different aspects of antenna engineering, including:

·  near and far field characterization of antenna performance;

·  theory of operation / analysis methods / design procedure for certain antenna types (wire, printed, aperture, reflector,…);

·  theory, analysis and design of finite and infinite arrays;

·  antennas for narrow/multi/broad-band operation;

·  feeding techniques;

·  numerical analysis methods for different antenna configurations…

Goal                     To provide a background level necessary for successful research in the area of antenna engineering

Disabilities

If you qualify for accommodations because of a disability, please submit to me a letter from Disability Services in a timely manner so that your needs may be addressed.  Disability Services determines accommodations based on documented disabilities.  Contact: 303-492-8671, Willard 322, and  www.Colorado.EDU/disabilityservices

Religious observances

Campus policy regarding religious observances requires that faculty make every effort to reasonably and fairly deal with all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance.  I presume that if these observances are important to you, you already know the dates. Please email me with these dates in the first week of class and I will move the midterms or schedule a make-up exam as needed.  The campus policy is at http://www.colorado.edu/policies/fac_relig.html

In-class behavior

Students and faculty each have responsibility for maintaining an appropriate learning environment. Students who fail to adhere to such behavioral standards may be subject to discipline. Faculty have the professional responsibility to treat all students with understanding, dignity and respect, to guide classroom discussion and to set reasonable limits on the manner in which they and their students express opinions.  Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, culture, religion, politics, sexual orientation, gender variance, and nationalities.  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.  See polices at http://www.colorado.edu/policies/classbehavior.html  and at http://www.colorado.edu/studentaffairs/judicialaffairs/code.html#student_code

Honor code

All students of the University of Colorado at Boulder are responsible for knowing and adhering to the academic integrity policy of this institution. Violations of this policy may include: cheating, plagiarism, aid of academic dishonesty, fabrication, lying, bribery, and threatening behavior.  All incidents of academic misconduct shall be reported to the Honor Code Council (honor@colorado.edu; 303-725-2273). Students who are found to be in violation of the academic integrity policy will be subject to both academic sanctions from the faculty member and non-academic sanctions (including but not limited to university probation, suspension, or expulsion). Other information on the Honor Code can be found at http://www.colorado.edu/policies/honor.html  and at http://www.colorado.edu/academics/honorcode/

Discrimination and Sexual Harassment  

The University of Colorado at Boulder policy on Discrimination and Harassment (http://www.colorado.edu/policies/discrimination.html, the University of Colorado policy on Sexual Harassment and the University of Colorado policy on Amorous Relationships applies to all students, staff and faculty.  Any student, staff or faculty member who believes s/he has been the subject of discrimination or harassment based upon race, color, national origin, sex, age, disability, religion, sexual orientation, or veteran status should contact the Office of Discrimination and Harassment (ODH) at 303-492-2127 or the Office of Judicial Affairs at 303-492-5550.  Information about the ODH and the campus resources available to assist individuals regarding discrimination or harassment can be obtained at  http://www.colorado.edu/odh
