Is there a way to set metal boundaries using the ctl interface, other than by
explicitly placing metal blocks?
Yes, you need to call a lower-level function (meep::fields::set_boundary)
e.g.
(init-fields)
(meep-fields-set-boundary fields Low X Metallic)
(meep-fields-set-boundary fields High X Magnetic)
sets the boundary in the +x direction to be a perfect electric conductor
and the boundary in the +y direction to be a perfect magnetic conductor.
(Perfect electric conduction boundaries are the default unless you use a
k-point, which makes periodic the default.)
With the C++ interface, how does one specify metals, or more specifically,
metallo-dielectric structures?
Perfect metals can be specified just by making epsilon very large and
negative (e.g. -1e20). To get realistic metals you need to use dispersive
materials.
