hi lukas,
i don't know about meep, but in mpb what you suggest works just fine.
you can build up complex structures by sequentially defining the
simple geometric shapes. the unit cell is just grid of points with a
dielectric value (or matrix, really) at each point.
when you put a simple geometric shape in your geometry list, mpb
figures out which points in the grid that shape occupies, and writes
the dielectric information associated with the shape into the grid.
then it goes to the next item in the list and repeats the process. so
if your shapes overlap, the last one to be written into any given grid
point is what is used in the calculation.

Hello,
I try to simulate the case of more superposed dielectric structures
overlapping each other. If I well understood, the geometric structure is
overlapped by other if the latter is defined lately in the source code. I
wouold like to ask then if mpb or meep support defined overlapping and can
model the case of three geometric shapes mutually superimposed.
Cheerful
Lukas Oliva
