摘要：
The work deals with the study of metamaterial hollow-core cylindrical (MHC) waveguides. In the article the solution of Maxwell's equations to analyse a MHC waveguide is presented. A dispersion equation was obtained in the form of a determinant. We created the computer algorithm in MATLAB language to investigate the dispersion properties of the MHC waveguide. The MHC waveguide was studied in the frequency range from 75 to 115 GHz with different waveguide parameters (radius, azimuthal index). We have analysed the dependences of the MHC waveguide main and higher order modes' dispersion characteristics on a waveguide radius and an azimuthal index.
