(a) The spacer and the grid, the 3D printed elements of the fabricated multilayer structures with their mean sizes. (b) The assembly of grids and spacers to build a structure made of a square lattice of rods with 4 layers. Other structures were assembled with 1 to 14 layers of rods. (c) Sketch of the THz beam line used for the experiments (see main text for details).
