The model of capacitively coupled intrinsic Josephson junction array and its chaotic behavior
本征约瑟夫森结阵列的Pspice模型及混沌行为研究

The model of capacitively coupled intrinsic Josephson junction array was constructed with the software PSpice. Taking advantage of this new model, we investigated the behavior of capacitively coupled intrinsic Josephson junction array driven by constant current. The time domain wave, freguency spectrum, fractal dimension and phase portrait were obtained. Compared with the uncoupled array, chaotic behaviors were found firstly in the capacitively coupled intrinsic Josephson junction array. The results are valuable for the research and application of intrinsic Josephson junction arrays.
