Abstract This article presents an application of the fractional derivative concept to the modeling of the time‐domain propagation in dispersive Cole‐Cole media. A recursive finite‐difference(SINGLEBOND)time‐time‐domain (FDTD) formulation is developed to solve the special differential equation that is obtained. This formulation is validated by comparing the calculated permittivities to analytical values. © 1996 John Wiley & Sons, Inc.
