which is identical to the FLW model . Similarly when θ = 0, same expression as Equation 3 can be derived with the sole presence of D2 . using Equation 3 with D1 and D2 , respectively. Here we assume D1 = 10 -10 cm 2 /s and D2 = 10 -11 cm 2 /s. The green dash line, exhibiting anomalous diffusion, is modeled using PDW (Equation ) with both D1 , D2 , and θ = 0.5. By adjusting these three parameters, various anomalous diffusion impedance response can be simulated.
