Abstract

IV-characteristics of a long Josephson junction with normal edges were calculated. Boundary conditions were modeled as shunts which consist of resistances, inductances and capacitances. IV-curves revealed self-induced resonant steps (zero-field steps) near voltages corresponding to frequencies of even-order modes of geometrical resonances (even Fiske steps). The dependence of the difference between resonant frequencies on the reciprocal length of the junction is in agreement with the theory. Conditions of the application of the model for the description of intrinsic Josephson junctions in high-temperature superconductors are discussed.
