Course Contents
This course consists of two parts. In the first part,
three basic electromagnetic processes are considered, namely: radiation from arbitrary current-distributions; scattering of given incident fields by arbitrary inhomogeneous objects; imaging and inversion of objects using the scattered field data. We derive, and analyze in Matlab the full-vectorial three-dimensional electromagnetic radiation formulae in frequency and time domains. The following subjects are also discussed: numerical solution of the scattering problem, inverse source, and inverse scattering problems. The second part of the course is devoted to the guided waves, where the modal structure of the electromagnetic field in open and closed planar waveguides is analyzed.
Study Goals
Understanding of the mathematical structure of the Maxwell’s equations, spatial and temporal structure of the electromagnetic field in open and closed configurations. Ability to manipulate with three-dimensional electromagnetic formulae in both frequency and time domains and to make controllable approximations. Knowledge of the basic principles of simulation of elementary radiators via evaluation of analytical expressions in Matlab. Understanding of the physical meaning of mathematical expressions and simulation results. Elementary knowledge about the discretization of an integral equation and the associated error. Understanding of the imaging principles and the ill-posed nature of inverse source and inverse scattering problems.
