摘要

Based on the analysis of the negative permeability properties of double split-ring-resonator array (SRRA), a simplified structure called single SRRA was proposed and demonstrated. The negative permeability properties of single SRRA are confirmed by software simulation, and the relationship between frequencies intervals corresponding to the negative permeability and single SRRA s structured parameters was investigated. Finally, the structure of single SRRA was improved by a quasi-Ω-like metallic pattern and a compound material with negative index of refraction was obtained.
