In this article the Modal Expansion Theory (MET) is developed for 2D metamaterial cylindrical waveguides. A new code based on 2D Finite Element Method (FEM) is implemented to compute conformal surface impedances. The MET using this FEM code is successfully applied to waveguides with different-invariant metamaterials. For such cases, computation time is at least 30 times faster than the commercial software HFSS.
