Outline of Final Research Achievements

The practical application of the superconducting filter, it is important to develop a technique that center frequency of a filter can be sifted to the higher frequency side, however until now, only method that can be shifted to a lower frequency side was reported. We examined the center frequency shift of the superconducting filter to the higher frequency side using a superconducting resonator tuning rod. Using superconducting-resonator tuning rod, placing the rods in a suitable position on the superconducting resonator, we found that the shift of the filter center frequency was higher frequency side. Also, metamaterial can be constructed using many resonators, therefore we can understand the useful of metamaterial tuning rods to shift the center frequency of the filter to the higher frequency side.
