Requisites: Before taking this module you must ( take PH20014 OR take PH20061 ) AND ( take PH20017 OR take PH20063 ) AND ( take PH20020 OR take MA20223 OR take PH20107 )
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.

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.

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