New Graphene Material Model
Graphene is now modeled using a surface conductivity
Treating graphene as a 2-D material leads to faster simulations
Two new components were added to the GUI in FDTD and MODE:
• New surface conductivity model was added to the material database
• Surface object was added to the list of geometric primitives
𝜎 𝜔, Γ, 𝜇 𝑐, 𝑇

Lumerical's TCAD software includes features for building
complex structures from external data sources
From external CAD software: STL Import
From layout: GDSII Import and Layer Builder
New feature: Dataset Builder
Create a structure from an existing finite element data source
 2D and 3D data supported
DEVICE: add an imported doping profile
