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. %G English %2 https://enac.hal.science/hal-02440149/document %2 https://enac.hal.science/hal-02440149/file/Kuhler_Modal_Analysis_of_Cylindrical_Waveguides_with_2D_metamaterial_Wall.pdf %L hal-02440149 %U https://enac.hal.science/hal-02440149 %~ UNIV-TLSE3 %~ ENAC %~ CNRS %~ CNES %~ LAPLACE %~ LAPLACE_GRE %~ TOULOUSE-INP %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP
