The first part of the course is concerned with the propagation and interaction of electromagnetic radiation as employed in remote sensing situations. Even before it reaches the antenna the radiation must pass through cables and waveguides, and this also involves propagation and interaction. Fundamental to all of this are Maxwell's equations and an understanding of what they can tell us. The second part of the course provides an introduction to advanced materials with an emphasis on their structural and magnetic properties. The various structural states and phase diagrams are considered in terms of microstructure and its influence on mechanical properties. Finally, the basic theories of magnetism and the different types of magnetic materials are described and the use of modern magnetic materials is discussed with particular reference to permanent magnets, transformers, and data storage.
