The icon_attribute button includes options to add the following attributes:

 

icon_eh_import Index Perturbation: np density & temperature

The Index Perturbation grid attribute consists of 'np density' and 'temperature' grid attributes, accounting for the refractive index changes due to the electron-hole density as well as the temperature. These grid attribute data can be recorded on a finite-element mesh in a CHARGE, HEAT, DGTD and FEEM simulation.

 

icon_permittivity_rotation Permittivity Rotation (FDTD only)

The Permittivity Rotation grid attribute allows users to add an arbitrary Euler rotation to the dielectric tensor. The main parameters are the "angle convention" and the Euler angles theta/phi/psi.

 

icon_LC_orientation LC Orientation (FDTD only)

The LC Orientation grid attribute allows users to specify arbitrary orientations for the Liquid Crystal director. The main parameters are the angles theta/pi (specifying the LC orientation), and the dielectric tensor will be set accordingly.

 

icon_matrix_transform Matrix Transform (FDTD only)

The Matrix Transform grid attribute allows users to add an arbitrary unitary matrix to the dielectric tensor. The main parameter is the unitary matrix U.
