| Aim: The course is intended to give a good knowledge about various types of electromagnetic systems of interest for technological applications as well from a fundamental point of view. |
|||
| Prerequisites: (valid for students admitted to programmes within which the course is offered) Participation in NFYA32, Electricity. Passed the course NFYB32 Electromagnetic fields, and participated in NMAC51 Mathematical methods in physics, or equivalent. Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding. |
|||
| Organisation: The course is presented in lectures. |
|||
| Course contents: Maxwell�?Ts equations on differential form are derived and potentials are introduced. Fourier transforms are used extensively. Several different, complementary, methods are used to solve the Laplace and Poisson equations: separation of variables; conformal mapping; analytical functions; mirror images. Multipole expansions are discussed. The rest of the course can be divided into wave generation and wave propagation. In the first part the radiation from accelerating charges is treated. We introduce Lienard-Wichert potentials and antenna theory. We discuss how fields are generated in practical applications, like in the microwave oven. We study wave propagation in different materials and at interfaces, especially at metal surfaces. Finally, relativistic electrodynamics is treated and 4-vectors are introduced. A complementary short course in complex analysis is given, which contains a compulsory home-work problem. This makes, among other things, the student familiar with analytical functions, which is important for the deeper understanding of several parts of the course. |
