Design of coupling network for persistent dynamics. (a, b) Design philosophy to setup a closed loop feedback mechanism shown as a block diagram (a) and as an electromechanical circuit (b). Meminductor branch current iw influences the state variable X which in turn influences the resistance of the parallel branch Rp. Change in Rp results in a change in iw thus repeating the cycle. The parallel branch is realized as a light-dependent-resistor (LDR), whose resistance depends on the position of an LED attached to the winding thus coupling Rp to X. (c) Electrical circuit representation of the setup. (d) Picture of experimental setup showing the LDR being illuminated by the LED attached to the winding.
