The normal derivative of the potential is the normal component of the electric field. This boundary condition means that the surface charge density is zero everywhere on the boundary and, according to Gauss law, you have no net total charge in the interior of the boundary.

Electromagnetic waves on boundaries When an electromagnetic wave is incident on a boundary between two materials, part of the energy in the wave will be transmitted across the boundary, and some of the energy will be re ected.
This can be explained as follows. From standard electromagnetic boundary conditions, Dz should be continuous between the incident layer and the slab. Thus a ...
30.01.2021 · The four boundary conditions for fields adjacent to perfect conductors are presented below together with the more general boundary condition from which they follow when all fields in medium 2 are zero: ˆn ∙ ¯ B = 0 [ from ˆn ∙ (¯ B1 − ¯ B2) = 0] ˆn ∙ ¯ D = ρs [ from ˆn ∙ (¯ D1 − ¯ D2) = ρs] ˆn × ¯ E = 0 [ from ˆn × (¯ E1 − ¯ E2) = 0]
18.12.2014 · The boundary conditions, as noted in the comment below the original post, are: \begin{align*} E_{1z} &= E_{2z} & \epsilon_r E_{1y} &= E_{2y} \\ B_{1y} &= B_{2z} & B_{1z} &\approx B_{2z} \end{align*} The "approximate equals" sign above is because we're assuming $\mu_1 \approx \mu_2$.)

The boundary conditionsmust not be confused with the interface conditions. For numerical calculations, the space where the calculation of the electromagnetic field is achieved must be restricted to some boundaries. This is done by assuming conditions at the boundaries which are physically correct and numerically solvable in finite time. In some cases, the boundary conditions resume to a simple interface condition. The most usual and simple example is a fully reflecting (…
