| Outline of Final Research Achievements |
We created a complex coiled coil (vector-potential coil) to generate a curl-free vector potential. The vector-potential coil that use a long flexible solenoid wound around a hollow cylinder. A voltage across a secondary conductor is proportional to the time rate of change of the primary current. We also present the transparency properties of the vector potential through a thick metal whose thickness is larger than the skin depth at the test frequency. Moreover, we replaced the hollow cylinder with a hollow superconducting cylinder, which provides an ideal magnetic shielding. However, even with this magnetic shielding, the voltage induced across the secondary coils (both superconductor and copper) remains the same as in the case of the nonmagnetic nonconducting hollow cylinder.
This approach can form the basis of new types of electrical equipment with unique characteristics not only in the quantum-mechanics regime but also in the macroscopic regime.
