Outline of Final Research Achievements

To enhance the performance of Superconducting Quantum Interference Device (SQUID), a new electromagnetic simulation method was developed. The developed simulation method can take into account the phenomenon of fluxoid quantum. Also, a new robust optimization method was developed to optimally design a thin superconducting magnetic shield over a SQUID. In addition, to reduce a magnetic noise in future, a new simulation on fluxoid moving was also developed.
