Transmission characteristics of Quadruple-Ridge Square Waveguide loaded with right-handed and left-handed materials

摘要

This paper presents a numerical study of the dielectric loaded Quadruple-Ridged Square Waveguide (QRSW). The dispersion characteristics of left-handed and right-handed material-loaded QRSW are first investigated by the edge element method. The variations of the cut-off wavelength and single-mode bandwidth with the ridge dimensions for different values of dielectric constant are studied in detail. The numerical results in this paper provide an extension to the design for the ridge waveguide and are helpful in practical applications for millimeter waves.
