NEGATIVE VALUES. “The first terahertz metamaterials able to achieve a desired magnetic response, which included negative values for permeability, were passive materials. Because of this, “tuning” was achieved by fabricating a new material, with slightly altered dimensions to create a new response. However, the notable advance, or practical achievement, is actually demonstrating the manipulation of terahertz radiation with metamaterials.”
