摘要：
In this paper, we study tunable metamaterial structures whose unit cell has triangular split ring resonator and wire strip for S-and C-microwave bands. Three types of new metamaterials, concentric and non-concentric configurations, are designed, and their electromagnetic response is investigated. Constitutive and S parameters are computed using retrieval algorithm to demonstrate the properties of the proposed new metamaterial designs. In addition, the electric field distribution on the metallic parts of the structure is illustrated for one design of the each sample. It is shown that the studied new metamaterials exhibit double negative properties in the frequency region of interest. The main advantage of this study based on the proposed structures is having the tunability in terms of the substrate thickness and the possibility of pronounced loss reduction.
