Aim

Electromagnetic waves are the final link on which modern communication relies, and are hence of fundamental importance for today's society. This course treats how electromagnetic waves propagate in different materials and structures, which has applications in wireless and wired communication systems, scattering theory, and non-destructive testing.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to explain the basic methods of analysis that are used for wave propagation in linear materials
• be able to account for simple material models such as the Debye and Lorentz models
• be able to account for concepts such as polarisation, wave impedance, different wave velocities, boundary conditions, causality, and passivity

Competences and skills
For a passing grade the student must

• be able to calculate reflection and transmission from isotropic materials at oblique incidence for interfaces, slabs, and multilayer structures
• be able to analyze wave propagation in homogeneous bianisotropic materials
• be able to analyze pulses and ray beams using frequency analysis and plane waves
• be able to carry through numerical simulations of wave propagation problems both by running simple self-produced codes, and commercially available software
• carry through a minor project including written documentation and oral presentation

Contents

The Maxwell equations and boundary conditions. Constitutive relations. Energy relations. Time harmonic fields. Plane waves, polarisation. Plane wave propagation in complex materials (isotropic, anisotropic, gyrotropic, bi-isotropic). Reflection and transmission at normal and oblique incidence for interfaces, slabs, and multilayer structures. Beams and the paraxial approximation. Wave propagation in inhomogeneous materials. Numerical methods e.g. finite difference methods and raytracing.
