Abstract

The effect of self-resonant modes in the absence of external magnetic fields in Josephson junctions is investigated by solving the Josephson equation. The method is based on the assumption of no external magnetic field but includes a dc bias and open-ended cavity boundary conditions. One finds a series of even-mode current singularities in the dc current-voltage characteristics. The method also provides theoretical explanations of the Q-value dependence (Q is the quality value in the resonance cavity) of the current singularities, the behavior of the cutoff voltage, and the maximum height of the first even-mode current singularities as found experimentally.
