Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

Basic courses in electromagnetics and numerical analysis and some
knowledge of MATLAB.

Aim

Numerical solution of Maxwell's equations plays an increasingly
important role in modern electrical engineering. Improvements, both in
computer technology and numerical algorithms, make it possible to
solve many electromagnetics design problems by computations, rather
than the traditional way by building and testing prototypes. This
holds in as diverse areas as eddy current calculations for generators,
electrical machines and transformers, microwave circuits and antennas,
optical components, radar scattering and electromagnetic
compatibility.

The course introduces the main methods in Computational
Electromagnetics: Finite Differences, Finite Elements and the Method
of Moments and applies them to model problems. Applications from
different areas of electromagnetics are used to illustrate the
strengths and weaknesses of the methods. The course aims at enabling
the student to choose appropriate methods for realistic
electromagnetics problems.

Learning outcomes (after completion of the course the student should be able to)

* Formulate and implement a basic computational algorithm in
electromagnetics with
> the finite-difference scheme,
> the finite-element method and
> the boundary-element method.
* Perform basic assessment of the numerical error.
* Distinguish between different sources that contribute to the
numerical error.
* Use basic extrapolation techniques.
* Choose between time, frequency or eigenvalue analysis for a given
electromagnetic problem.
* Choose appropriate numerical technique for a given application.
* Choose appropriate post-processing tools for a given application.
* Operate commercial software in an well-informed manner.
* Evaluate the computational resources required to analyze a given
industrial problem.

Content

hree main computational methods are studied in the course

* Finite Differences for electrostatics and wave propagation in one,
two and three dimensions. Staggered meshes for Maxwell's equations -
FDTD (Finite-Difference Time-Domain, or Yee's method). Application
to computation of capacitance and S-parameters of microwave
circuits.

* The Finite Element Method (FEM) in one and two dimensions. Nodal and
edge elements. Galerkin's method and variational
formulations. Application to microwave cavities, magnetostatics and
eddy current problems. (Introduction to three-dimensional eddy
current calculations and commercial software.)

* The Method of Moments (MoM). Integral formulation of electrostatics
and Maxwell's equations. Green's functions and numerical
integration. Application to capacitance calculation and
electromagnetic scattering from a thin wire.

Error estimates and extrapolation to zero grid size are studied by
grid refinement.

Organisation

The course is organized as lectures and exercise classes. The classes
are oriented towards hand-in problems (MATLAB) dealing with
application problems.
