DESCRIPTION – summary of the module content (100 words)

This module is taken by BSc students in stage 3. It develops students' knowledge of electromagnetism, quantum mechanics and illustrates the aspects in common and relationships between the two areas. It builds on the Stage 2 core modules PHY2021 (Electromagnetism I) and PHY2022 (Quantum Mechanics I). The starting point is the Maxwell equations introduced in PHY2021, which are manipulated to obtain the electromagnetic wave equation and the form of the solutions.

The dielectric and magnetic properties of atoms and materials are considered from both a classical and quantum perspective, 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. Methods of guiding electromagnetic waves of different frequency by transmission lines, waveguides and optical fibers are discussed and this knowledge, along with the theory of quantum transitions is used to understand maser and laser operation.

This is a core module for BSc Physics programmes and is supported by BSc Stage 3 tutorials.

MODULE AIMS – intentions of the module

The module aims to develop students' understanding of quantum mechanics and Maxwell's equations and their applications including some advanced topics, fomalism and applications to the point where they will be able to engage with contemporary research literature. Students will gain an in-depth understanding number of interesting physical phenomena that are important in a wide variety of areas and in many key technologies.
