“…Electrically insulating materials with fractal properties such as conductive α-radioactive chemical substances are referred to as fractal radioisotopic composite materials [24,25]. The particular important aspects of such materials are not limited to them exhibiting nonstationary trackstructure [26], nonlinear properties of fractal layers [27,28] increased irreversibility, and the memory of fractal materials with the specificity property of 'forgetting' or 'information loss' [29] and lastly the electron system forming non-equilibrium states as a consequence of the radioisotopic inclusion [30].…”

The resistive-capacitive shunted Josephson junction (JJ) with fractal properties is scrutinized in this paper. The rate equations betelling the fractal resistive-capacitive shunted Josephson junction (FRCSJJ) are established and have for the external biasing direct current (DC) source less than or equal to 1 two equilibrium points and no equilibrium point for the external biasing DC source greater than 1. Stability characterization by the Routh-Hurwitz critic indicates one stable equilibrium point called the ‘‘stable node’’ and the other unstable referred to as the ‘‘saddle-node’’. Current-voltage (C-V) characteristics depict the sensitivity of the hysteresis loop to the two fractal parameters. With an external alternative current (AC) source used in biasing FRCSJJ, the model exhibits periodic bursting oscillations, periodic oscillations, reverse period-doubling route to chaotic oscillations, different shapes of chaotic dynamics, and mutual interaction between complex oscillations and period-4-oscillations. Finally, the accomplishment of the microcontroller implementation of FRCSJJ establishes the quantitative agreement with numerically obtained dynamics.
