Community News - metamaterials and superconductors

Posted on August 11, 2015

We have previously reported on research to engineer superconductors with higher critical temperatures using metamaterial concepts. Further work has been reported on the SPIE website, suggesting that a "[p]lasmonic metamaterial geometry may enable fabrication of an aluminum-based metamaterial superconductor with a critical temperature that is three times that of pure aluminum."

Superconductors offer the promise of loss-less transmission, and are also used in applications like magnetic resonance imaging. Increasing the critical temperature reduces the cost and complexity of the associated equipent required to place materials into a superconducting state. We will continue to watch this work with interest!
