Phys 7120
Electrodynamics II
Spring 2017

Class Meets: Lectures 10:45 am - 12:40 pm, Monday and Wednesday, LS 107.

Instructor: Oleg Starykh, 304 JFB, Email: starykh `at' physics.utah.edu

Office Hours: Thursday, 3 - 4 pm, or by appointment.

Teaching Assistant (grading): Mr. Hassan Allami

Textbooks: the course is mostly based on my lecture notes. The recommended (but not required) textbook for the class is D. B. Melrose and R. C. McPhedran, Electromagnetic processes in dispersive media. [Book's info: ISBN-10: 052101848X ; ISBN-13: 978-0521018487 ; paperback version is published by Cambridge University Press (August 22, 2005). Amazon webpage of the book is here.]

This book provides a useful perspective which we plan to use in discussing waves in media. In addition, the following books might be helpful: Landau and Lifshitz, The Theory of Fields; Jackson, Classical Electrodynamics; Brau, Modern Problems in Classical Electrodynamics.

Course Description Electrodynamics II is a second part of the year-long graduate course.

Homeworks are due on Wednesdays at 10:45 am (before the start of the class). There will be no homeworks in the weeks immediately after a midterm.

Course Objectives: This is a core first-year graduate class whose main objectives are

1. to lay down the foundations of the understanding of the field theory, including development of important math skills in applications of tensor algebra, partial differential equations, vector calculus, etc., essential for physicists of all later specializations;

2. to acquire working knowledge of the broad spectrum of electromagnetic phenomena, including practical ability to analyze them qualitatively as well as quantitatively; the problems to be addressed during this course will range from classical ones in electrostatics to modern applications, such as plasmonics.

Main topics to be covered: field of moving charges, radiation, waveguides, and electrodynamics of linear, dispersive media.

Previous semester's web page (Fall 2016, Electrodynamics I, taught by Prof. Pesin) is here.

Course requirements Lecure and discussion section attendance is expected. No late homeworks are accepted unless there is an explicit agreement with the instructor regarding this.

Grading policy and exams: 10 highest-score homeworks, 15 points each (33.3%); 2 midterms, 75 points each (33.3%); final test 150 points (33.3%); no make-up test/assignments unless for legitimate reasons: emergency (documented), university-approved travel, etc.
