An Inverstigation on Zero Cutoff Frequency in a Rectangular Waveguide Periodically Loaded with MNG Metamaterial

E. Mobini and F. Mohaje

Abstract—In this paper the propagation of electromagnetic wa-ve inside a waveguide which is periodically loaded with anisotropic metamaterial with transversal negative permeability and positive permittivity (MNG) is analyzed. Using Maxwell’s equations and Fluquet’s theorem, dispersion equation of the structure is derived and discussed. The obtained equation is general and valid for propagating and attenuating modes in both anisotropic MNG and air medias. Our study is mainly concentrated on the existence of the zero cutoff frequency in a rectangular waveguide which is periodically loaded with MNG metamaterial .All simulations are done for two different thicknesses of MNG layers and the achieved results are compared with the results of a hollow waveguide. Results indicate that the electromagnetic dispersion curve, zero cutoff frequency, stopband and passband intervals can be highly affected by the permeability and the thickness of the layers.

Index Terms—MNG metamaterial, zero cutoff frequency
