布局动量模拟中的用户定义材料用户是否可以定义自己的材料？

布局动量模拟中的用户定义材料除了ADS中的默认模型外，用户是否可以定义自己的材料？
例如，我在没有原理图的布局中直接设计了一种模块，我想在布局中尝试动量模拟。
这种材料很不寻常。
多层衬底具有频率依赖的介电常数，磁导率和损耗角正切，而这些参数对频率的依赖性不是典型的Svensson / Djordjevic类似的。
查找表比表达式公式更好地提供依赖性。
我希望以下自动模拟可以完成，而我不知道如何实现它：1，在每个频率，我通过DAC组件从外部文件中读出基板定义。
2，将这些定义传递给模拟器。
3，启动布局动量模拟器。
4，将模拟结果输出到每个频率的外部文件。
5，迭代所需的每个频率。
你能告诉我如何实现上述任务吗？
实例是优选的。
而且，原理图中似乎没有用户AEL扩展的界面。

  User defined Materials in layout momentum simulation
Is it possible for a user to define his own materials besides default model in ADS?
For example, I design a kind of module directly in layout without schematic and I want to try momentum simulation in layout. The material is unusual. The multilayered substrate has a frequency dependent permittivity, permeability and loss tangent, while these parameters’ dependency to frequency is not a typical Svensson/Djordjevic similar. The dependency is better to be provided by a lookup table than an expression formula. I hope that the following automatic simulation could by done while I have no idea how to implement it:
1, At each frequency, I read out the substrate definitions from an outside file by DAC component.
2, Transfer these definitions to the simulator.
3, start the layout momentum simulator.
4, Output the simulation result to an outside file at each frequency.
5, iterate each frequency required.
Would you please tell me how to implement the above task? Examples are preferred.  
Moreover, there seems to be no user AEL extensions’ interface as in the schematic.
