Reply To: I need to use light source for my project

you have two questions:

1: 2D material with dispersion

2: simulation source

For 2D conductivity material, you can import data. Please refer to Creating new sampled data materials in FDTD it is the same as permittivity/index in terms of data. You can select add/2D sample data in material database.

Modulator usually is based on waveguide. If your THz modulator is a kind of waveguide with the 2D material, you can use mode source or port. Please visit this example: Spatial soliton in a graphene-embedded waveguide
