I keep receiving the error attached in the picture. Does anyone know how to resolve this? I am applying the polder tensor to a material.
Hello Sean,
Feko doesn't allow active materials and … checks for assessing the passivity are present for both isotropic and anisotropic media based on the conservation of energy.
So the following conditions should be satisfied.
Eps tensor must be Hermitian.
Mue tensor must be Hermitian
2. For ferrite loss-free material -> deltaH = 0
Eps tensor must be Hermitian (actually it will have always off-diagonal entries equal to zero)
Mue tensor must be antisymmetric
3. For ferrite with losses
Mue tensor is not Hermitian
Hopefully, it will help you overcome the error.
Best regards,
Jaehoon
