Hope you know the more basic one: D=(epsilon0)E + P,
where in general case P should be wrote as a function of E,
not necissarily linear to E. So use Taylor exapnsion to
get the equation:
D=(epsilon0)E + (epsilon1)E^2 + (epsilon2)E^3 + ...
You should note that E is a vector so for higer order of E,
epsilon is in fact a 张量(don't know the name in English,xixi).
Even for the first order, epsilon1, if the material is not a
isotropic(各向同性) one (as usually for those crystals), then
epsilon1 shoul
