Electric Displacement Field

$\mathbf D$

The electric displacement field is a vector quantity defined as the electric field strength multiplied by the permittivity of the medium through which it passes:

$\mathbf D = \varepsilon \mathbf E$

where:

$\varepsilon$ is the permittivity of the medium

$\mathbf E$ is the electric field strength

Its $\LaTeX$ code is \mathbf D .
