Comparison of electric coupling with magnetic coupling between the Josephson tunnel junction and applied microwaves
Abstract
The electric coupling and the magnetic coupling between the Josephson tunnel junction and applied microwaves have been studied separately. The theoretical analysis (based on the forced vibration model) and experimental results indicate that for a half-wavelength junction only even microwave-induced steps can be obtained under magnetic coupling, but for the electric coupling, odd steps appear simultaneously, and that for an integral wavelength junction only even steps can be observed under the two couplings. The efficiency of the electric coupling, according to the theory and the experimental results, is found to be better than that of the magnetic coupling for the Nb-NbO(x)-Pb junction.
