Okay, so now I am a little bit confused. Why, if we are assuming a more complicated form of the constitutive relations, is the dielectric function scalar and not a vector function? If there are dependencies on the position shouldn't the dielectric function be a vector function? Is this a...

Does anything change if we assume the medium in non-local?

What conditions are necessary to use the constitutive relations for Maxwell's equations? I am working in a nonlinear media, but am a little confused about whether I can assume isotropy or not. If I am assuming the media is nonlinear is it necessarily anisotropic? Or, is it possible to have...
