Asking for help, clarification, or responding to other answers. This leads to the following definition: electric flux density The electric flux density D = E, having units of C/m 2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential. If the defects (cavities, . The vector $\mathbf D$ is called the electric displacement (field).is defined as $\displaystyle \mathbf {D} \equiv \varepsilon _{0}\mathbf {E} +\mathbf {P}$, where $\displaystyle \varepsilon _{0}$ is the permittivity of free space, and $\mathbf P$ is the (macroscopic) density of the permanent and induced electric dipole moments in the material, called the polarization density. a magnitude and direction. Inserting that into the previous equation, MathJax reference. While we won't give it a rigorous definition here, it can be sufficiently understood for the purposes of antenna theory as being proportional to the Electric Field. $$ The expression of electric field at a point is given by Where, Q is the charge of the body by which the field is created. I am not sure If I understand it entirely, why would using neglect the effect of polarization? After substituting this into electric flux density the equation becomes.
