有限尺寸顺磁体/超导体圆柱形斗篷的磁探测能力
Magnetic detectability of a finite size paramagnet/superconductor cylindrical cloak
摘要：
本文研究了同轴顺磁壳包围的有限厚度II型超导管对静磁场的屏蔽。伦敦和麦克斯韦方程组的精确解的基础上，它表明，完美的隐身是可实现的任意几何参数，包括薄膜的情况下，两个成分。与以前的近似研究假设超导体成分的完全抗磁性，它被证明，隐形提供同时完全不可检测性，即结构的磁矩完全消失，以及所有高阶多极矩，只要外部均匀场保持不受影响。
英文摘要：
Cloaking of static magnetic fields by a finite thickness type-II superconductor tube surrounded by a coaxial paramagnet shell is studied. On the basis of exact solutions to the London and Maxwell equations, it is shown that perfect cloaking is realizable for arbitrary geometrical parameters including the thin film case for both constituents. In contrast to previous approximate studies assuming perfect diamagnetism of the superconductor constituent, it is proven that cloaking provides simultaneously full undetectability, that is the magnetic moment of the structure completely vanishes as well as all high-order multipole moments as soon as the uniform field outside remains unaffected.
