Abstract

We present the experimental characterization of planar terahertz metamaterials based on rectangular electric split-ring resonator designs. Comparisons to square-ring designs reveal that rectangular shapes greatly affect the overall metamaterial response by altering the spectral separation and coupling between multiple ring resonances. A simple model is used to help us understand this coupling behavior and the extent of its effects. Advantages and disadvantages of these unconventional ring designs are discussed in terms of possible applications.
