3D Anisotropic Medium

Diagonal tensor

Define the diagonal permittivity and permeability tensors by defining up to three dielectrics constituting the medium properties along the UU, VV and NN axes. If no linear dependencies exist between two axes, enter 0. A value of 0 indicates empty or zero. Use the text, Free space, to indicate the free space medium.

Figure 1. The DI - Set medium properties dialog, for Anisotropic medium, set to Diagonal tensor.

Full tensor

Define the permittivity and permeability tensors by defining up to nine dielectrics constituting the medium properties along the UU, UV, UN, VU, VV, VN, NU, NV and NN axes. If no linear dependencies exist between two axes, enter 0. A value of 0 indicates empty or zero. Use the text, Free space, to indicate the free space medium.

Complex tensor

Define the permittivity and permeability tensors by using complex values. An entry in the tensor may be a complex number, pure real number or a pure imaginary number, but not 0.
