Does anyone know how to write the diffusion tensor (coefficient) for a isotropic media?
It should be a matrix but I can't find it in the literature. Maybe you guys know it or can help.
Jackson doesn't have it.

Cheers

Thanks Andy, I'm very sorry, I'm stupid, I'm looking for "diffusion tensor for an ANISOTROPIC media", not isotropic.

Again, sorry.

Then make the tensor not proportional to the identity matrix. Not sure what the off-diagonal coefficients correspond to, physically.
