Figure 6: Fractional-order frequency-dependent pinched hysteresis loops of the floating fracmemristor operating at (a) incremental mode and (b) decremental mode. For the grounded fracmemristor operating at (c) incremental mode and (d) decremental mode. For all cases: = 0.99 (light blue line), = 0.75 (light red line), = 0.5 (light green line), = 0.25 (light cyan line), and = 1 m (light magenta line).
