Abstract
This paper is a review of various techniques used in computational electromagnetism such as the treatment of leaky modes in waveguides, helicoidal geometries for microstructured optical fibres and the design of arbitrarily shaped invisibility cloaks. This seemingly heterogeneous list is unified by the concept of geometrical transformation that leads to equivalent materials, i.e., the change of coordinates is completely encapsulated in the material properties. The practical set up is conveniently made via the finite element method (FEM).
