The Propagation Characteristics of 2-D Metamaterial Waveguides Using the Modal Expansion Theory
Year: 2018
Type: article
Abstract: In this paper, the modal expansion theory (MET) is applied to 2-D metamaterial cylindrical waveguides. A new code to compute the surface impedances with 2-D finite-element method (FEM) is put forward. The surface impedances depend on the frequency and the incidence angle. The characterization of propagation in a 2-D metamaterial waveguide is presented by using the MET and 2-D FEM. Comparisons with the software HFSS are carried out in order to validate the new method.
