Perfect Electric Conductor Boundary Condition¶

The perfect electric conductor (PEC) boundary condition is applied at boundaries with conducting materials, whose conductivity is assumed to be infinite. This is a good approximation at the boundaries with metals at high field frequencies. Under this boundary condition the tangential component of the electric field's amplitude \(\tilde{\mathbf{E}}\) at the boundary is set to zero:

where \(\hat{\mathbf{n}}\) is the unit vector normal to the boundary.

To create a PerfectElectricConductorCondition, the user must specify a custom name for the condition and provide the boundary Marker:

condition = PerfectElectricConductorCondition(
    name = "My Perfect Electric Conductor Boundary Condition",
    marker = my_marker,
)
