By the end of the term, successful students should be able to do the following:
- Obtain the transmitted wave that propagates through media by
considering the effects of the electronic properties of molecules.
- Solve for the radiation due to oscillating current distributions.
- Solve for the radiation due to various antenna configurations.
- Understand the general solution to the Helmholtz equation in the
radiation zone as a multipole expansion and how to obtain each term from
given source distributions.
- Examine the effects of scattering of waves by media at various
- Learn how to apply the essentials of Einstein's theory of
relativity to electromagnetic phenomena. We consider especially
relativistic kinematics, the electromagnetic field tensor, covariance
thereof and the relativistic precession of spin.
- Study the motion of charged particles in electromagnetic fields
using the action principle.
- Understand and compute the energy loss of charged particles in
dense media; understand Cherenkov radiation and transition radiation;
study Bremsstrahlung radiation emitted during charged particle
collisions with nuclei. [We will cover as much as time allows here.]
Students are expected to know electrodynamics at the PHYS 703
level before they take this course. Only students who have done
well in PHYS 703 should take this course. Also, students should know
mathematical methods of physics.
Classwork in the form of presentations and / or class participation and
/ or tests will prepare students for the real world of research /
teaching / industry. 10% of the total course grade is based on these.
There have been some misunderstandings regarding scope and topics of
presentations in the past. Hopefully, the following helps clarify by
emphasizing certain simple points:
- Scope: when in doubt, omit additional points. Try not to make a
comprehensive talk. 5 minutes is a very short time. Try to make only
one point and make it clearly.
- Topic: Generally speaking, it means what it says. For example:
"Experimental observation of" means an experimental observation of
(whatever is specified). It does not mean a "theoretical derivation
of". It does not mean a "gedanken experiment explaining". It does not
mean an experimental observation of something completely
different. If you do not understand a topic, it does not mean you are
free to talk about something else. It means you must come and discuss
the topic further with me (in advance, and not 5 minutes before the
lecture). Bottom line: Stick to the topic!
Students are evaluated through the semester using class participation,
homework, in-class tests as well as a final exam.
Students turning in less than 70% of homeworks will automatically earn
an F grade. For other students, the course score will be calculated as
Classwork: 10%, Homework: 30%, Test 1: 10%, Test 2: 10%, Final Exam: 40%.
Homework problems will be assigned every week and will
be due at the Wednesday lecture of the next week.
Homework that is up to one week late earns 50% points; after that no
credit will be given.
The course content is derived from a variety of sources, including the
- Jackson, John David. "Classical Electrodynamics", John Wiley & Sons, 3rd
Edition. ISBN: 047130932X.
Griffiths, David. "Introduction to Electrodynamics", Prentice Hall, 3rd
Edition. ISBN: 013805326X.
[This is a highly recommended accompanying text.]
In this course we focus on a study of electromagnetic wave propagation
through media (and waveguides), a relativistic formulation of
electrodynamics and also applications of Maxwell's equations to
radiation, diffraction and charged particles. Thus, we aim to cover
important topics from the second half of the textbook by Jackson,
In the previous semester's prequel to this course, i.e., in PHYS 703,
the basic concepts of electrodynamics are covered: electrostatics,
multipoles, dielectrics, magnetostatics, Maxwell Equations,
electromagnetic waves and waveguides, i.e., we cover most of Chapters
1-6 in the textbook by Jackson.
