# Κλασική Ηλεκτροδυναμική (Φ-509)

## Κωνσταντίνος Τάσσης

This is a graduate course on classical electrodynamics that will cover most basic topics and a selection of specific topics. The philosophy of the course is to guide you in the vast field of electrodynamics and encourage you to delve deeper into the topics that are closer to your interests (e.g. the topics that are related to your research). This course is addressed to postgraduate students as well as undergraduates with the appropriate background. It requires a good background in basic knowledge of Electromagnetism (Courses PH-301 and PH-302) as well as mathematical methods of physics (such as the course PH-311).

This is a graduate course on classical electrodynamics that will cover most basic topics and a selection of specific topics. The philosophy of the course is to guide you in the vast field of electrodynamics and encourage you to delve deeper into the topics that are closer to your interests (e.g. the topics that are related to your research). For this reason a big part of the course is a project on a topic that you will select, you will write a thorough report on and present at the end of the semester instead of a final exam.

**Course Material**

** **

The course will cover the following topics organized in 6 sections as follows:

- Quick Review of basic Electrodynamics: Maxwell’s equations in vacuum and in matter, waves, electromagnetic potentials, electromagnetic energy and momentum, Poynting theorem, Plane waves, monochromatic waves, polarization.

- Electromagnetic waves: EM waves in dielectrics, reflection and transmition of EM waves, Snell’s law, Fresnel equations, dielectric constant as a function of frequency, dispersion relation, EM waves in Plasmas, Faraday rotation, EM waves in conductors

- MHD: Derivation of magnetohydrodynamic equations from the Boltzmann equation, ideal MHD, non-ideal terms.

- Waveguides: TM, TE, TEM waves, dispersion relation, energy transport in waveguides, resonant cavities

- Radiation: solution of Maxwell’s equations with sources, retarded potentials, field of accelerating point charge Lienard-Wiechert potentials, radiation from linear accelerators - bremsstrahlung radiation, cyclotron and synchrotron radiation. Radiations from extended sources, antennas.

- Special Relativity: Lorentz transforms, covariant formalism of Electrodynamics

**Grading **

At the end of almost each section there is going to be a test on the material covered in that section, so there is going to be ~5 tests through the semester. Your grade will be determined 50% by your performance on the exams at the end of each section and 50% by the written report and the presentation on the topic of your choice.
