Abstract
We report development and measurement of a micro-fabricated compact high-temperature superconducting (HTS) metamaterial atom operating at a frequency as low as ∼ 53 MHz. The device is a planar spiral resonator patterned out of a YBa2Cu3O7−δ thin film with the characteristic dimension of ∼ λ0/1000, where λ0 is the free-space wavelength of the fundamental resonance. While deployment of a HTS material enables higher operating temperatures and greater tunability, it has not compromised the quality of our spiral metamaterial atom and a Q as high as ∼ 1000 for the fundamental mode, and ∼ 30 000 for higher order modes, are achieved up to 70 K. Moreover, we have experimentally studied the effect of the substrate by comparing the performance of similar devices on different substrates.
