This is the second electromagnetism module taken by Physics students. It builds on PHY2021 (Electromagnetism I) and covers fundamental physics that students are capable of directly observing. The early part of the module provides a brief recap and reinforces the difficult material treated at the end of PHY2021. The Maxwell equations are stated and manipulated to obtain the wave equation, and the form of the solutions discussed. The dielectric and magnetic properties of solids are then introduced, with emphasis on the frequency dependence of their real and imaginary components, and the consequences for wave propagation. Wave propagation at interfaces between dissimilar materials is considered, leading to derivation of Fresnel reflection and transmission coefficients. The need to guide electromagnetic waves of different frequency is discussed, and guiding by transmission lines, waveguides and optical fibers is introduced. Finally the electromagnetic fields generated by charges moving with uniform or oscillatory velocity are discussed. A number of interesting physical phenomena are considered that are important in a wide variety of areas and in many key technologies. This is a core subject for Physics programmes and is supported by Stage 3 tutorials and problems classes.
The module aims to develop students' understanding of Maxwell's equations and their applications including some advanced topics. Specifically, students will get to the point where they can handle the fundamentals of fields due to moving charges and also to begin to explore the interaction of electromagnetic radiation with matter.
