Effects of Microstructure Variations on Macroscopic Terahertz Metafilm Properties

Effects of Microstructure Variations on Macroscopic Terahertz Metafilm Properties

The properties of planar, single-layer metamaterials, or metafilms, are studied by varying the structural components of the split-ring resonators used to comprise the overall medium. Measurements and simulations reveal how minor design variations in split-ring resonator structures can result in sign...
