There is currently no easy way to import a HDF5 file (or similar grid-based dataset) for the dielectric function. That is, there is no built-in function for this. However, it is possible, in principle. First, you should consider whether it is necessary. The geometric primitives provided by the .ctl interface are general enough to describe most geometry, and for very weird shapes you can just specify the dielectric function as an arbitrary user-defined function of position. Since you can specify the dielectric function as an arbitrary user-defined function of position, you are free in principle to load your grid of dielectric values into a matrix, and then have your function interpolate into that matrix as needed. (In the Scheme interface, this will be rather slow, but if performance is a concern you can do it quickly in the C++ interface.) Regards, Steven G.
