While Lumerical optical solvers come with a default library that includes large amount of materials, it is possible that you might want to add a new material that you want to use in your simulation. There are several ways how to do this:

  1. Obtain material data from third party source or measure them if
    you have the equipment and import them from file:
    http://kb.lumerical.com/en/materials_creating_sampled_data_material.html

  2. Use analytic function do describe your material properties:
    http://kb.lumerical.com/en/materials_analytic_material_model.html

  3. Use the basic permittivity or refractive index material models that are supported by material database. You can modify the model parameters in the property panel. See the following KB page for full list of supported basic models:
    https://kb.lumerical.com/en/index.html?materials_permittivity_models.html

  4. Use one of the advanced material models that come with FDTD
    (requires you to obtain appropriate coefficients):
    http://kb.lumerical.com/en/materials_advanced_material_models.html

If you do not have the material data or the related analytical formula on hand, it is good idea to try a quick Google search e.g. “In2O3 refractive index”. There is a good chance that you will find the data for the material of your interest.
Also publications using similar materials or focusing on similar applications tend to be a good resource.

Once you import your material into Lumerical, it will be saved in the simulation file, but it will not be available in the default material library that is loaded when you start a new project. To modify the default materials that appear when you create a new simulation:

  1. Locate the defaults sub-directory of the installation. By default it will be located at:

Windows: C:\Program Files\Lumerical\FDTD\defaults
Linux: /opt/lumerical/fdtd/defaults
Mac: /Applications/Lumerical/FDTD\ Solutions/FDTD\Solutions.app/Contents/Resources/defaults

  1. Copy the default simulation file to your desktop. Optionally, you may also want to make a backup of this file.

  2. Open the file on your desktop and make all required modifications to the material database in this file. This might include deleting unused materials and creating new materials.

  3. Copy this file back into the defaults sub-directory. This generally requires Administrator access.

  4. Next time you start the product, the updated material database should appear automatically.

But how can i add graphene???i used the data to create a new material.but can it have the property of graphene?Please helpme to solve this problem.Thanks in advance

Hi. FDTD provides two models for graphene. A legacy 3D volumetric model and a pure 2D surface conductivity model. To learn about these models please check out this KB page.

The different input parameters used in the 2D surface conductivity model is also described nicely in this KX post: Scattering rate in surface conductivity of graphene.
