How can I define arbitrary geometric objects in Meep? In particular, the dielectric structure I'd like to simulate is a two-dimensional polygon with a large number of vertices.
The most efficient thing, if you have a shape with flat surfaces, is to build it out of the primitive shapes. For example, it's quite easy to make a hexagon out of three blocks.
Alternatively, you can use the material-function type in order to make your dielectric function an arbitrary function of position, as specified by a Scheme function that you write. This is more general (e.g. if you want to specify some weird curved shape, or a continuous variation of epsilon), but the simulation will start up more slowly.
