*Default*: None
:boundary:
The boundary condition for the surface. This can be "transmission",
"vacuum", or "reflective".
The boundary condition for the surface. This can be "transmission",
"vacuum", "reflective", or "periodic". Periodic boundary conditions can
only be applied to x-, y-, and z-planes. Only axis-aligned periodicity is
supported, i.e., x-planes can only be paired with x-planes. Specify which
planes are periodic and the code will automatically identify which planes
are paired together.
*Default*: "transmission"
:periodic_surface_id:
If a periodic boundary condition is applied, this attribute identifies the
``id`` of the corresponding periodic sufrace.
The following quadratic surfaces can be modeled:
