We present the modelling of twisted electromagnetic waveguides using helicoid coordinates. This amounts to introducing equivalent inhomogeneous anisotropic materials which are however taken into account easily by the finite element method. An interesting property of such helicoid coordinates is to preserve the intrinsically two-dimensional nature of the problem.
