COURSE
DESCRIPTION		 PHY 4183/5083 (Electromagnetic Radiation) is a senior/graduate-level introduction to the application of electromagnetic theory (Maxwell's Equations) to time-dependent electromagnetic fields.  Applications to transmission lines, wave guides, microwave communications, antenna theory, and fiber optics are studied in some detail.  As time permits, course topics will include:  
  1. Maxwell's Equations - Brief summary of observational basis of Maxwell's Equations of electromagnetic theory, electromagnetic fields in matter, boundary conditions, Poynting's Theorem  

    2.  
  2. Transmission Lines - Circuit model of transmission lines, the Telegrapher's transmission line equation, transmission of harmonic waves and impulses, using Smith charts, power transmission and line impedance, the standing wave ration, non-ideal lines and impedance matching  

    3.  
  3. Plane Waves - Wave equation from Maxwell's equations, phasor techniques for solving Maxwell's equations, wave polarization, reflection and transmission of EM plane wave at material interfaces, waves obliquely incident upon a boundary
  4. Waveguides - Metallic waveguides, planar wave guides and microstrips, cavity resonators, power losses in a cavity (Q of a cavity), dielectric waveguides and optical fibers
  5. Antenna Theory - Dipole radiation, linear antennas, antenna arrays

PREREQUISITES A knowledge of vector calculus and differential equations at the level of PHY 3884 (Mathematical Physics I or its equivalent) is assumed. 

TEXTBOOK Classical Electromagnetic Radiation, 3nd Ed., by Mark A. Heald and Jerry B. Marion, 1995, Saunders College Publishing (REQUIRED). 

HOMEWORK Physics is a subject that can be learned only by doing many exercises and problems. Moreover, the examinations will consist of problems similar to those assigned as homework and those at the end of each chapter of your textbook. For this reason, weekly problem assignments will be made. These homework assignments will be collected at the start of the period on the date they are due. The homework will be graded and forms a significant portion of the grade received for the course. Late homework will not be accepted for any reason.  However, your two lowest homework scores will be dropped.  

Homework solutions should be neatly written on standard notebook-size (8.5" x 11") paper using one side only and each problem should be started on a new page. It is helpful if the pages are stapled together. For full credit, your homework problem solutions should clearly state the principle of physics and/or formula being used and fully explain all reasoning.

OFFICE HOURS Official hours are listed above, but I am usually around from 9 - 4 each day during the week whenever I am not teaching class. Please feel free to come by any time especially if you want to talk about physics or school.

EXAMS Official hours are listed above, but I am usually around from 9 - 4 each day during the week whenever I am not teaching class. Please feel free to come by any time especially if you want to talk about physics or school.

EXAMS There will be two exams given on the days indicated in the attached class schedule - a mid-term and a final.   A comprehensive final exam will be given on the scheduled date for this course - Wednesday, December 16 @ 5:30-7:20 PM. Exams will not be given early or late to accommodate individual schedules. Students who miss an exam should contact their instructor as soon as possible to schedule a makeup.  

Each exam will consist of problems similar to those at the end of each chapter of the textbook and those assigned for homework. All exams will be open note and open book.

GRADES  In general, grades will be class curved with a target class GPA of ~3.2 but in no event will the curve be higher than the strictest scale curve listed or lower than the minimum scale curve shown. While the target class grade distribution is typical, it or may not be achieved in any given class in a particular semester and is in no sense guaranteed. Grades will be based on a class curve bounded by the two scales below:  
 
  
              Points    (%) 
Mid-Term     150   (30%) 
Homework    200   (40%) 
Final            150   (30%) 
Total        500  (100%)		 Minimum Scale 
A (Above 75%) 
B (60% - 74%) 
C (50% - 59%)
D (40% - 49%) 
F (Below 40%)		 Strictest Scale 
A (Above 85%) 
B (75% - 84%)   
C (65% - 74%)   
D (55% - 64%)   
F (Below 55%)		 Target Grade Distribution 
A (~30% of Class) 
B (~60% of Class)   
C (<10% of Class)   
D (<5% of Class) 
F (~0% of Class)
 
STUDYING
PHYSICS		 You should expect to spend approximately two hours of outside class study for every hour in class in addition to approximately 4 to 5  hours doing a homework assignment. Many students find it helpful to form study groups to work and discuss homework assignments with other students. You are encouraged to do this. It is an excellent way to learn physics. However, it is expected that each student will know how to work each problem without help.  If you get stuck on a homework problem, see your instructor for help.

SPECIAL
ACCOMODATIONS		 Students with disabilities who believe that they may need accomodations in this class are encouraged to contact Equity Officer Brad Morellio at ext. 2573, or see me after class as soon as possible to better ensure that such accommodations are implemented in a timely fashion.
