Super Low Loss Guided Wave Bands Using Split Ring Resonator-Rod Assemblies as Left-Handed Materials

SRR metamaterial is used as a substrate material in a microstrip guided wave structure to determine what the effect is of a material with potentially excessive dispersion or loss or both. A Green’s function method readily incorporates the metamaterial permittivity and permeability tensor characteristics. Ab initio calculations are performed to obtain the dispersion diagrams of several complex propagation constant modes of the structure. Analytical analysis is done for the design and interpretation of the results, which demonstrate remarkable potential for realistic use in high frequency electronics while using the LHM for possible field reconfigurations. Bands of extremely low loss appear for several of the lowest order modes operating in the millimeter wavelength regime.
