Characteristics of the resonance and impedance of power-bus structure with the embedded metamaterial substrate

This paper conducts the research on the variation in the characteristics of the resonance and impedance of the metallic parallel plates due to the replacement of the normal dielectric substrate by the metamaterial. The ENG(¿<0), MNG(¿<0) and DNG(¿, ¿<0) types of metamaterial as well as the DPS(Double Positive) material are taken into consideration a full-wave modal analysis method known for accurate computation, as the SRR-kind of Lorentz model for permittivity and metal wire-periodic array-kind of Drude model for permeability, and the behaviors of parallel plates¿ resonance mode and impedance are observed. Based upon the observation, the design guidelines for the substrate can be addressed regarding how to suppress the parallel plates¿ spurious resonance modes that degrade the quality of the electronic equipment.
