WebThere are three things to note. First, there is a built-in function electric_energy_in_box which calculates the integral of $\vec{E}\cdot\vec{D}/2 = \varepsilon E ^2/2$.This is exactly the integral in the denominator, divided by 2. In cylindrical coordinates $(r,\phi,z)$, the integrand is multiplied by the circumference $2\pi r$, or equivalently the integral is over …
