Abstract
A metamaterial resonator structure having a size for resonating a predetermined frequency band. The resonator structure includes one or more dielectric slabs each having a top surface and a bottom surface. A conductive resonator element is configured on the top surface of each dielectric slab and has a crescent shape including a center portion and opposing rounded end portions defining a gap therebetween, where the center portion has a wider dimension then the end portions so that a width of the element gradually tapers from the center portion to the end portions, and where the conductive element has a diameter that is a fraction of a wavelength of the frequency band. Several dielectric slabs can be stacked on top of each other, where each slab has a different size and each conductive resonator element is a different size so that each resonator resonates a different portion of the frequency band.
