Goals: To develop the student's ability to analyze and understand static and time-varying electromagnetic fields and their applications, primarily in the communications area.

 

The following competencies should be imparted to the students:

 

Outcomes:

 

1. Understanding of electrostatic, magnetostatic and electromagnetic fields and their interaction with matter.

 

2. Ability to solve basic canonical electrostatic, magnetostatic and electromagnetic problems.

 

3. Understanding of electromagnetic wave propagation.

 

4. Ability to solve for the reflection and transmission of uniform plane waves at infinite planar interfaces.

 

5. Ability to evaluate transmission line problems including methods for impedance matching.

 

6. Ability to use commercial mathematics software for computing and visualizing electrostatic, magnetostatic and electromagnetics field problems.

 

Electronic Book: Visual Electromagnetics for Mathcad is now available and will be used during the semester for in class demonstrations and homeworks. It is also an excellent tool for you to use to enhance your learning and understanding of the subject material. MathCad Professional 7 is available in the PC lab in the Civil Engineering Building. The Visual Electromagnetics for Mathcad Electronic Book is also available in this lab. To access the electronic book: open MathCad (this is found under the start menu -> programs -> Math Soft Apps -> MathCad 7 Professional), then under the Help menu, select OpenBook..., then select Visualem.hbk from the window. It is also noted that the electronic book is freely distributed and available through the Visual Electromagnetics web page (http://www.engr.uky.edu/~visualem/).

 

 

Homework policy: Homeworks will generally be assigned each week on Monday and Thursday, due the following Thursday and Monday, respectively. The homework assignments will be distributed through the EE468G web page accessible from the URL listed above. The homework is to be turned in at the beginning of the class period. No late homework will be accepted. Solutions to all homework problems will be deposited in the class file (located in the Engineering Library) for your perusal or photocopying.

 

Exam policy: There will be four in class exams plus a comprehensive final exam. If you feel an exam problem was graded incorrectly, it must be re-submitted to the instructor within 24 hours from the time the exam was returned. Failure to write an exam will result in a score of zero. No makeup exams will be given. Upon prior notification of the instructor, allowances will be made under extreme circumstances.

 

Honor System: All work written in the exams must be your own. Failure to abide by this rule will result, at a minimum, in a zero score for the exam and/or further action following University of Kentucky regulations. Homework solutions can be discussed with your colleagues but the work you submit must be your own.

 

Attendance: If a student is to be absent from class for an extended period of time (two classes or more), the Instructor must be notified in advance, if possible, or by the second class of the absence. If such an inexcusable absence occurs, the student will lose all credit towards their class participation and potentially a drop in their letter grade.

 

Course Notes: The course notes are available in bound form at Johnny Prints, 547 S. Limestone. At the end of the course notes are review problems with solutions to be used as a study aide for each of the exams.

 

Grading Assignment will be based on your final grade for the course based on the three exams, homeworks, midterm project and final exam. The letter grade assignment will then be calculated according to the table below.
