Subfigures (a,b) represent Bode plots, while, subfigure (c) presents the Nyquist plot of a device with an equivalent model which includes a Warburg diffusion element. The equivalent circuit used to simulate the attached plots is presented in subfigure (d) and is widely known in electrochemistry as a Randles cell.
