  • Abstract
    A technique to reduce unwanted scattering by antennas is demonstrated which exploits the inefficiency of high-temperature superconductors above Tc. Electrically small dipole and loop antennas made of superconductors are modelled above and below Tc to predict their scattering efficiencies, and it is shown that a significant transition in radar cross-section occurs which justifies the use of superconductors over copper in stealth applications
