Further information on descriptions Description: Aims:
An aim of this unit is to provide a mathematical framework for the description of the radiation, transmission, reception and guidance of electromagnetic energy. A further aim is to introduce the interaction of electromagnetic waves with matter, focussing particularly on processes of absorption, reflection, luminescence and scattering within materials.

Learning Outcomes:
After taking this unit the student should be able to:
* describe dipole radiation using magnetic vector potentials;
* explain the basic features of guided modes in metallic, dielectric and fibre waveguides;
* derive expressions for the real and imaginary parts of the complex dielectric constant of a dipole oscillator;
* apply the dipole oscillator model to describe features in the optical response of dielectrics, semiconductors and metals;
* describe optical emission and absorption processes in terms of electronic band structure;
* outline the main physical principles underlying Rayleigh, Brillouin and Raman scattering.

Skills:
Numeracy T/F A, Problem Solving T/F A.

Content:
Transform methods in optics (3 hours): Review of wave theory of light. Fraunhofer diffraction. Introduction to Fourier optics.
Radiation (3 hours): Electromagnetic potentials, retarded potentials, near and far fields, radiation from a Hertz dipole.
Guided waves (6 hours): Metal and dielectric waveguides, optical fibres.
Introduction to optical processes in materials (3 hours): Absorption, emission, scattering. Complex refractive index and dielectric function. Material classes and electronic band structure.
Lorentz model (3 hours): Application to describing the optical properties of insulators and the interaction of light with lattice vibrations.
