Hi Gary,
OK, we wont go there. Dialectric tensor is for the case where the
dialectric material is anisotropic. The tensor is a 3x3 matrix of
permitivities that describes the dependency of the Displacement field in
each of the x, y, and z directions on the permitivity (e) matrix of e11,
e12, e13, ... e33 and the E field in x, y, and z direction . [D] = [e] [E]
example: Dx = e11*Ex + e12*Ey + e13*Ez
