| Outline of Final Research Achievements |
We focused on the vector potential, which is the basic physical quantity of electromagnetism, and worked on a new approach to measure the impedance distribution inside the object. We show that spherical vector potential coil generates uniform vector potential by theory and numerical simulation. Furthermore, we actually built a coil and measurement system. In addition, a first voltage component equal to the line integral of the inner product of the time derivative of the vector potential and the conductor path, a second voltage component proportional to the resistance along the line integration path were also observed. The electromagnetic shield was ineffective for the first voltage and effective for the second voltage. By using these properly, a new measurement method will be realized.
