  dielectric function
The calculations are based on the exactly solved model of a sharp metal/electrolyte interface, the model of a Born sphere for the ion, and the three-mode approximation for the dielectric function of the solvent.
      
Parameters of the analytical expression used for the dielectric function ε(k) of the solvent are selected so as to reproduce the results of calculations of the ε(k) function obtained by a molecular dynamics method.
      
The complex dielectric function of the films was determined from the experimental data by dispersion analysis of the reflection spectra.
      
This effect is related to the fact that a contribution to the dielectric function of slow ions, determining the scattering amplitude, depends on both spatial and frequency dispersion.
      
The k-dependent semiclassical dielectric function is employed instead of the Lindhard-Mermin expression.

It is very difficult to calculate and simulate the propagation of electromagnetic wave in a complicated dispersive medium using the FDTD method because of the complication of the dielectric function in it.So it is indispensable to modify the conventional Maxwell equations to make the most of FDTD equations more independent of the dielectric function and more convenient for the generalization of programs.Then the calculation is made for the electromagnetic field of complicated dispersive medium by using Z-transform into FDTD Finally, simulation in one dimension is given The Z-transform in this method simplifies the calculation and programming for complicated frequency-`dependent medium with FDTD method.

在使用FDTD法计算仿真电磁波在复杂色散媒质中的传播时,由于介电参数的复杂性往往给实现带来很大的困难,因此有必要对常规的Maxwell方程做出修改,使得FDTD迭代式能更独立于媒质函数,有利于程序通用化;基于此使用Z变换法把FDTD法应用到复杂色散媒质电磁场计算中;最后给出了一维情况下的仿真图.使用上述Z变换法可以简便对于色散媒质FDTD法计算和编程.
