Any portion of the objects that are outside of the unit cell are ignored by default. However, if you set the input variable ensure-periodicity? to true, it will "wrap the object around" to the other side of the unit cell, i.e. it implicitly makes all of the objects repeat periodically, as documented in the manual. In any case, whenever you are confused by something like this, the simplest thing is just to try it, and look at the resulting epsilon.h5 file.
