Engineering Electromagnetics
Thus, because this is a density and because it is derived from the electric field,
we will call it the electric flux density. The use of the term "flux"' will become
apparent in the following chapter. We merely want to comment here that the use
of this ...
Thus we define the electric flux density at a point in an electric field as where
ΔΦE is the electric flux through an area ΔA which is perpendicular to the direction
of the flux and is a unit vector along the direction of the flux (that is, perpendicular
...

surface over which the integral is performed need not be a surface corresponding
to some particular physical feature of the problem. The law states that the equality

Introduction to Electromagnetic Engineering
Electric Flux Density. We now introduce a vector function having charge density
as its flow source. Thus, by definition, V - D = q, (4-2) where D is called electric
flux density* However, Eq. (4-2) does not by itself specify D uniquely and it must ...
