| Abstract: | Taking advantage of the software PSpice,we used RCSJ model to simulate the I-V characteristics of the Josephson junctions under the radiation of microwave.Integers as well as subharmonic constant voltage steps are observed.We also obtained the relations between the height of subharmonic steps and the amplitude of RF current.The results are valuable for the research and application of Josephson junction in voltage standard and microwave detection. |
