# FullyAnisotropicMedium
Fully anisotropic medium including all 9 components of the permittivity and conductivity tensors. Provided permittivity tensor and the symmetric part of the conductivity tensor must have coinciding main directions. A non-symmetric conductivity tensor can be used to model magneto-optic effects. Note that dispersive properties and subpixel averaging are currently not supported for fully anisotropic materials.
Note: Simulations involving fully anisotropic materials are computationally more intensive, thus, they take longer time to complete. This increase strongly depends on the filling fraction of the simulation domain by fully anisotropic materials, varying approximately in the range from 1.5 to 5. Cost of running a simulation is adjusted correspondingly.
