"Electrodynamics" is an fundametally important theory course for undergraduate students majored in physics. The course systematically teachs the basic rules of electromagnetism, properties of electromagnetic field and its interaction with charged matter. The course also includes an introduction to special relativity.
The major contents of the course include: The energy momentum tensor of electromagnetic wave, Maxwell equation and Lorentz equation; Variable separable method, mirror-image method in solving static electric and magnetic field, Green`s function method; The concept of gauge transformation and electromagnetic gauge invariance and their physical meaning; Propagation and radiation of electromagnetic field; The interaction between a moving electrically charged particle and elctromagnetic field; Special relativity, it historical background and experimnetal facts, fundamental priciples of special relativity and Lorent transformation, space-time theory of special relativity; The propagation, dispersion and dissipation of electromagnetic field travelling in the medium.
Physics
物理（Physics）是一门自然科学，也是绝大多数科学的基础学科，注重于研究物质、能量、空间、时间，尤其是它们各自的性质与彼此之间的相互关系。从广义来说，物理学探索分析大自然所发生的现象，以了解其规则。物理专业主要分应用物理、生物物理、原子物理、核物理、粒子物理、量子物理、凝聚态物理、等离子物理、高能物理、天体物理与宇宙学等多种专业分支。
