You set bloch periodic boundaries by using (set! k-point ...) as described in the manual. There is no problem combining Bloch periodic boundaries with PML -- PML is not a boundary condition, it is a material placed adjacent to the boundary, and is independent of the boundary condition used. See the holey-waveguide example in the Meep manual, which uses a mix of PML and Bloch-periodic boundaries in the last part of the example (computing the eigenmodes). Regards, Steven G.
