I've used the mpb code for some weeks and I'd like to know if its possible to construct solid shapes like tetrahedra.
Yes, you can do this by overlapping multiple blocks (of air and/or dielectric). For example, any convex polyhedra should be constructible by starting with one block and chopping pieces off of it with blocks of air (and other methods could be devised).
(It seems like an interesting abstract-geometry question to ask what is the minimum number of blocks, either adding or subtracting, required to make a given polyhedral shape.)
