• FREQUENCY-DEPENDENT LOD-FDTD METHOD FOR THE ANALYSIS OF THE COLE-COLE MODEL

抄録

type:Article

The purpose of this article is to develop an LOD-FDTD method for the efficient analysis of the Cole-Cole model, which is free from the CFL condition. The Z-transform technique is utilized to translate the Cole-Cole expression into the Z domain, in which a Taylor series expansion is applied to approximating the fractional order differentiators. To demonstrate the effectiveness of the present method, we analyze the response of THz radiation to a dry skin expressed by the Cole-Cole model. The computation time is reduced to 70% of the explicit method, when the time step is chosen five times as large as that of the stability limit, maintaining an acceptable accuracy.
